Fuzzy Adaptive Finite Time Command Filter Backstepping Control of Power System
Wangyao Xu,Ze Li,Guozeng Cui,Chengxi Wang,Fuyuan Hu 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.11
In this article, an adaptive fuzzy finite time command filter control scheme is first proposed for a single machine infinite power system with static VAR compensator (SVC). The unknown external interference is taken into account in the controller design, and the incomplete single machine infinite SVC power system is formulated in terms of fuzzy logic system. The devised adaptive backstepping control scheme employs command filter technology and finite time control theory. Further more, it is proven that the designed controller ensures the rotor power angle in the power system converge to the expected value and all variables of the control systems are semi-global practical finite-time stable (SGPFS). Finally, simulation results are presented to show the effectiveness of the proposed control scheme.
Finite-time Secondary Frequency Modulation of Microgrid Based on Event Triggering Mechanism
Chenglong Zhou,Ze Li,Guozeng Cui,Yifan Chen,Wangjun Hao 제어·로봇·시스템학회 2024 International Journal of Control, Automation, and Vol.22 No.4
This paper designs a ratio consistency algorithm based on event triggering mechanism aiming at the frequency recovery deviation caused by traditional droop control in microgrid. It achieves secondary frequency modulation in microgrid by adjusting the active power setting value. The max-min consistency algorithm is proposed to realize asymptotic consistency of distributed power supply in a finite time. Communication delay is added to ensure the accuracy of frequency update and verifies the robustness of the algorithm against itself. Meanwhile, the validity of event triggering conditions is verified. Finally, the simulation examples are carried out to prove the correctness and superiority of the proposed finite-time control strategy.
Proportional Integral Observer-based Consensus Control of Discrete-time Multi-agent Systems
Renyang You,Mingzhu Tang,Shenghui Guo,Guozeng Cui 제어·로봇·시스템학회 2022 International Journal of Control, Automation, and Vol.20 No.5
The multi-agent consensus control is widely used in industrial application, such as industrial robot, satellite attitude control, etc. Therefore, this paper studies the consensus control problem of multi-agent systems. For discrete-time Lipschitz nonlinear multi-agent systems with unknown inputs, a consensus control algorithm based on proportional integral observer is proposed. Firstly, a proportional integral observer is designed for each subsystem to estimate the system states and unknown input signals simultaneously. Then, a consensus control protocol based on the system state estimation is designed, and H∞ technique is used to effectively suppress the unknown input signals. Furthermore, the gain matrices of the observer and consensus control are obtained by solving a linear matrix inequality. Finally, two simulation examples show the correctness and feasibility of the proposed method.
