Software Architecture of Control System for Heterogeneous Group of Mobile Robots

This article describes the software architecture, which can significantly reduce development time, provide an effective process of data exchange and control of mobile robots (or a group of mobile robots). This architecture is based on representation of a mobile robot as the composition of mechatronic devices connected in a hierarchical graph of software interactions (also known as middleware systems). This architecture provides high robustness, capacity and transmission frequency of control commands and data. Also, successful results have been achieved in providing dynamic reconfiguration of system components without stopping as well as automatic crash recovery (including complex interaction graphs) and auto-configuration.

Design of a Plugin Split-Parallel Chevrolet Malibu: Control Strategy Development

As a selected participant in the EcoCAR2: Plugging In to the Future competition, headline sponsored by General Motors and the US Department of Energy, the Rose-Hulman team has completed the second year of a three year design cycle. This paper focuses on the supervisory control system design completed during year one of the competition including plant model development, control system hardware architecture, control system software architecture, vehicle operational modes, automated testing, and fault detection and mitigation.

The software architecture of a SAN storage control system

We describe an architecture of an enterprise-level control system that addresses the issues of management for area network (SAN) -attached block devices in a heterogeneous open systems environment. The control system, also referred to as the storage virtualization engine, is built on a cluster of Linux®-based servers, which provides redundancy, modularity, and scalability. We discuss the software architecture of the control system and describe its major components: the cluster operating environment, the distributed I/O facilities, the buffer management component, and the hierarchical object pools for managing memory resources. We also describe some preliminary results that indicate the system will achieve its goals of improving the utilization of resources, providing a platform for advanced functions, using off-the-shelf hardware components and a standard operating system, and facilitating upgrades to new generations of hardware, different hardware platforms, and new functions.

Minimization of blocking time in component-based software architecture for control systems

In this paper, the architecture of Port-Interface Component Architecture for Real-time system Design (PICARD) is briefly introduced. PICARD is a software architecture and environment for rapid development of application control systems using pre-compiled software components. When a control task has to run at a high frequency, its maximum blocking time should be minimized. Because components are developed and compiled separately, it is not easy to apply traditional methods to reduce blocking time. Two methods are proposed for PICARD to reduce the maximum blocking time. These methods are efficient and easy to implement. PICARD is successfully applied to build a CNC controller, and its real-time characteristics is analyzed.

Control Software System of a Turbogas Power Unit

A third generation control software system for turbogas power units, in a series of modernization projects, is presented. Main objective was to reduce the complexity of its predecessors, to facilitate the integration of new control strategies to enhance the unit’s performance. The automation, control and protection functions performed by previous generations served as requirement specifications. Adaptation of a generalized functional structure for industrial process control in defining the control system software architecture became the project key point. Real-time structured design, and programming lead to the desired higher quality system. Successful integration of a fuzzy speed controller fulfilled the objective.

PRISM

This paper presents a process for the reengineering of computer-based control systems, and describes tools that automate portions of the process. The intermediate representation (IR) for capturing features of computer-based systems during reverse engineering is presented. A novel feature of the IR is that it incorporates the control system software architecture, a view that enables information to be captured at five levels of granularity: the program level, the task level, the package level, the subprogram level, and the statement level. A reverse engineering toolset that constructs the IR from Ada programs, displays the IR, and computes metrics for concurrency, communication and object-orientedness is also presented.

Also described is the design of hypermedia techniques that enhance the usability of the reverse engineering tools.
