ADRC‐based transient air/fuel ratio control with time‐varying transport delay consideration for gasoline engines

This paper presents a fuel injection controller based on the modified active disturbance rejection control (ADRC) algorithm to maintain the air/fuel ratio (AFR) at the stoichiometric value in the presence of a transport time delay. The factors affecting the dynamics of the AFR include the variations of the intake manifold pressure, engine speed, and load torque, as well as uncertain parameters existing in the fuel film evaporation and the oxygen sensor aging, which are viewed as the 'total disturbance' to the AFR system and estimated by the extended state observer (ESO). Thus, based on the Lyapunov–Krasovskii functional stability theory, the ADRC fuel injection controller is designed with the gain matrices of the controller and observer and solved by employing linear matrix inequalities. Considering the time‐varying transport delay, a time delay block is added to the ESO. By synchronizing the input signals of the ESO, the performance in terms of the timely compensation for the disturbance is improved. The effectiveness of the proposed control strategy is validated through simulation of a V6 spark ignition engine model developed by the Society of Instrument and Control Engineers (SICE) Research Committee on Advanced Powertrain Control Theory. © 2017 Institute of Electrical Engineers of Japan.

Message from Editors-in-Chief

It is our great pleasure to congratulate the Journal of Advanced Computational Intelligence and Intelligent Informatics (JACIII) on its 20th anniversary. The concept of Computational Intelligence was originally authorized in the first IEEE World Congress on Computational Intelligence (WCCI) held in Orlando, Florida in 1994, where the key issues of CI were characterized by fuzzy, neuro, and EC (Evolutionary Computation). The JACI (Journal of Advanced Computational Intelligence) Vol.1 No.1 was published from Fuji Technology Press in Oct 1997, and the name of the journal has been changed to JACIII since Vol.7 No.1 Feb 2003 to accept more widely developed issues related to intelligent informatics. The JACIII is currently published in bimonthly, six issues a year, in cooperation with International Fuzzy Systems Association (IFSA), Japan Society for Fuzzy Theory and Intelligent Informatics (SOFT), Brazilian Society of Automatics (SBA), The Society of Instrument and Control Engineers (SICE), John von Neumann Computer Society (NJSZT), Vietnamese Fuzzy Systems Society (VFSS), Fuzzy Systems and Intelligent Technologies Research Society of Thailand (FIRST), Korean Institute of Intelligent Systems (KIIS), and Taiwanese Association for Artificial Intelligence (TAAI), and is indexed in ESCI, SCOPUS, and COMPENDEX (Ei-Index). In the past 20 years personally, so many issues happened in the JACIII editing process. Some of them were very tough but all are very good memories to us. We occasionally organize the JACIII editorial meetings in Tokyo and remotely. As Editors-in-Chief, we are most grateful to all who have worked with the JACIII and helped reach its 20th anniversary. We thank the editorial board members for editing this journal with their high discernment and the guest editors for arranging special issues with their high profession. We would also like to thank the peer reviewers for their accurate evaluations in a short time, and finally our special thanks go to the editorial office of Fuji Technology Press Ltd., especially to its founder, Mr. K. Hayashi, and to the editors, Ms. Reiko Ohta and Mr. Kunihiko Uchida for their efforts in publishing this journal.

Identification of Static Boundary Model Based on Gaussian Process Classification

Due to the needs for CO2 emission reduction, the control region for automotive engine system is pushed toward the boundary between normal and abnormal engine operations such as knocking and misfiring. When an engine is operated outside of admissible region, the engine or the catalyst is seriously damaged or passengers feel very uncomfortable. Therefore the identification of the boundary is highly demanded. In this paper we propose a design of experiment (DoE) strategy based on the Gaussian process classifier (GPC) with the expectation propagation (EP) algorithm. In the experimental result, the proposed algorithm can identify the boundaries of an engine benchmark problem, provided by the joint research committee of the Society of Automotive Engineers (JSAE) and Society of Instrument and Control Engineers (SICE).

Molecular Robotics: A New Paradigm for Artifacts

The rapid progress of molecular nanotechnology has opened the door to molecular robotics, which uses molecules as robot components. In order to promote this new paradigm, the Molecular Robotics Research Group was established in the Systems and Information Division of the Society of Instrument and Control Engineers (SICE) in 2010. The group consists of researchers from various fields including chemistry, biophysics, DNA nanotechnology, systems science and robotics, challenging this emerging new field. Last year, the group proposed a research project focusing on molecular robotics, and it was recently awarded a Grant-in-Aid for Scientific Research on Innovative Areas (FY2012-16), one of the large-scale research projects in Japan, by MEXT (Ministry of Education, Culture, Sports, Science and Technology, JAPAN). Here, we wish to clarify the fundamental concept and research direction of molecular robotics. For this purpose, we present a comprehensive view of molecular robotics based on the discussions held in the Molecular Robotics Research Group.

Development of Energy Management of Hybrid Electric Vehicle for Improving Fuel Consumption via Sequential Approximate Optimization

This paper proposes a practical method for improving the fuel consumption of the energy management of hybrid electric vehicle (HEV). The society of automotive engineers of Japan (JSAE) and the society of instrument and control engineers (SICE) in Japan provides a benchmark model. First, the energy management system (EMS) is constructed with four design variables. The computation is so expensive that sequential approximate optimization (SAO) with radial basis function (RBF) network is used to find an approximate global optimal solution. Numerical result shows that the proposed algorithm of the EMS improves the fuel consumption significantly.

The Real Players [President's Message

I am writing this column just after the IEEE/Robotics Society of Japan (RSJ) International Conference on Intelligent Robots and Systems (IROS 2011), which was held 25–30 September in San Francisco. IROS 2011 is financially cosponsored by four organizations: IEEE Robotics and Automation Society (RAS), IEEE Industrial Electronics Society (IES), RSJ, and Society of Instrument and Control Engineers (SICE).

43rd International Conference on Decision and Control (IEEE CDC 2004)

Conference on Decision and Control (CDC) conducted every year by the Control Systems Society (CSS) of the International Institute of Electrical and Electronics Engineers (IEEE) is the oldest major conference on automatic control. It dates back to the First Symposium on Adaptive Processes held in 1962 in USA. Its popularity is explained by its high scientific level, quick publication of reports (three month after the last revision), and it is traditionally held in December, as a rule, at sites with warm climate. In the opinion of the Past and Present Chairmen of the Society [1], CDC is a historical rendezvous for the members of the Control Systems Society. where they can meet and know about latest advances, and where the sessions of the Council of Directors are held. It is here the Bode lectures are read, prizes are awarded, and Fellows of the Society are elected. The 43rd CDC was held in December 14–17, 2004 at the Atlantis Hotel, Nassau (The Bahamas) and sponsored by the Society for Industrial and Applied Mathematics (SIAM), Japanese Society of Instrument and Control Engineers (SICE), and European Control Association (EUCA). C. Cassandros (Boston University) and W. Gong (Massachusetts University) chaired the Organizing and Program Committees, respectively. The program included 936 sectional reports carefully chosen from a total 1879 submitted reports, i.e., less than 50% of submitted reports were approved. Russia was represented by G. Kurin (Voronezh Forestry Engineering Academy), D. Efimov (Institute of Mechanical Engineering, St. Petersburg) and I. The Russian delegation was sponsored by the Control Systems Society. The Conference was held in honor of the 50th CSS Anniversary to trace the development of the Society and Conferences on Decision and Control, as well as to review the state-of-the-art in control as a whole. Without going into details, I would like to outline my impression on the conference, which, in my opinion, may be of interest to the readers. First I would like to say a few words as to how reports are selected. Selection is rather strict and based on reviews of full texts of reports. Therefore reports are of high level, probably, higher than that of IFAC World Congress, for which about 65–70% of submitted reports are approved (though the number of reports at the IFAC Congress is usually greater). Reports are reviewed by the Conference Editorial Board consisting of more than 100 expert editors from different countries appointed by the Council of Directors of the Society for several years. Editors work on honorary basis and are independent of the Program Committee. Every report is assigned a set of key words in accordance with the theme of the paper for the editor. The editor forwards the reports to few reviewers and submits an approval or a rejection recommendation to the Program Committee on the basis of the reviews from at least two independent reviewers. Since the conference is held annually, there is less than ten months between the last date of submission of reports (March 1) and date of commencement of the conference, and about five months for reviewing
