A review of piezoelectric energy harvesters for harvesting wind energy

Microelectromechanical systems (MEMS) powered by conventional batteries are disadvantaged in terms of scope of application and environmental friendliness because their power sources need to be replaced regularly and have the risk of polluting the environment. Piezoelectric technology provides a solution for harvesting clean energy such as wind energy from the environment, achieving self-supply of electrical energy for MEMS, and meeting the requirement of without management and maintenance after installation. An overview of piezoelectric wind energy harvesting can help to connect the MEMS field and meet its self-supply needs. This paper presents a comprehensive review of state-of-the-art advances in piezoelectric wind energy harvesters (PWEH). The classification of piezoelectric materials is briefly introduced. The principle of its operation is introduced. It is divided into five categories by structure: bluff body, airfoil, flag, wind concentrator, and wind turbine structures. The research status of harvester has been discussed from four perspectives: structure, application, theoretical modeling, and signal processing. The existing literature is integrated, and the future development directions in three aspects: expanding application area, improving adaptive capabilities, and application-oriented system design are proposed. This paper provides references for people in the industry who are committed to structural innovation and performance enhancement.

A Comprehensive Memory Management Framework for CPU-FPGA Heterogenous SoCs

Efficient utilization of restrained memory resources is of paramount importance in CPU-FPGA heterogeneous multiprocessor system-on-chip (HMPSoC)-based system design for memory-intensive applications. State-of-the-art high level synthesis (HLS) tools rely on the system programmers to manually determine the data placement within the complex memory hierarchy. Different data placement policies may lead to different system performance, and finding an optimal data placement policy is a nontrivial problem. For instance, we show counter-intuitive results that traditional frequency and locality-based data placement strategy designed for CPU architecture leads to nonoptimal system performance in CPU-FPGA HMPSoCs. In this work, we first propose an automatic data placement framework for field programmable gate array (FPGA) kernels to determine whether each array object should be accessed via the on-chip BRAM, shared CPU L2-cache, or DDR memory to achieve the optimal performance. Moreover, we find that when the CPU kernel and the FPGA kernel are executed in parallel, memory contentions may degrade the performance and the optimal data placement policy designed for the FPGA kernel alone will not achieve the optimal overall system performance. In this article, we proposed to use cache partitioning to alleviate the impact brought by memory contentions. We extend the framework designed for FPGA by adding the cross-layer memory contentions analysis to automatically generate an optimal data placement policy and cache partitioning mechanism for the parallel executing kernels. The proposed data placement framework can be seamlessly integrated with the commercial Vivado HLS. The experimental results on the Zedboard platform show an average <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$1.5\times $ </tex-math></inline-formula> performance speedup for FPGA kernels compared with a greedy-based allocation strategy. When FPGA kernels and CPU kernels are executed in parallel, the FPGA kernel and the CPU kernel have a performance speedup of <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$1.62\times $ </tex-math></inline-formula> and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$1.10\times $ </tex-math></inline-formula> on average, respectively.

CT-Type MLI-Based PV System for Critical Loads Using SIMO DC–DC Converter

The availability of an uninterrupted power supply to loads is an important aspect of power system reliability and resiliency. With rising natural and human-made power system disruptions, the necessity for alternative renewable-based sources is becoming increasingly important. This article outlines a unique and efficient photovoltaic (PV) system design for a standalone application that keeps critical loads continuously powered in case of any grid power outages. The PV system proposed here uses a Cross T-Type multilevel inverter (CT-Type MLI) and single input multiple output (SIMO) DC–DC converter. The CT-type MLI improves overall system performance based on total harmonic distortion (THD), number of levels, number of components required, total standing voltage (TSV), cost factor per level, and efficiency. Moreover, the presence of an isolation transformer in the DC–DC converter eliminates the need for a bulky power transformer on the AC side of the converter, making the system more economical for grid integration. It also allows DC-link voltage to be bucked/boosted as per requirement.

Data-Driven Unsteady Aeroelastic Modeling for Control

Aeroelastic structures, from insect wings to wind turbine blades, experience transient unsteady aerodynamic loads that are coupled to their motion. Effective real-time control of flexible structures relies on accurate and efficient predictions of both the unsteady aeroelastic forces and airfoil deformation. For rigid wings, classical unsteady aerodynamic models have recently been reformulated in state space for control and extended to include viscous effects. Here, we further extend this modeling framework to include the deformation of a flexible wing in addition to the quasi-steady, added mass, and unsteady viscous forces. We develop low-order linear models based on data from direct numerical simulations of flow past a flexible wing at a low Reynolds number. We demonstrate the effectiveness of these models to track aggressive maneuvers with model predictive control while constraining maximum wing deformation. This system identification approach provides an interpretable, accurate, and low-dimensional representation of an aeroelastic system that can aid in system and controller design for applications where transients play an important role.
