作者： Shixi Hou Juntao Fei Yundi Chu jiangsu Key Laboratory of Power Transmission ＆ Distribution Equipment Technology

In this paper, a modified adaptive fuzzy control based on backstepping design（MAFCBD） is proposed for active power filter（APF） to attenuate the effect of unknown external disturbances and modeling uncertainties. Firstly, a backstepping control strategy for active power filter is proposed, which simplifies the design of the controller, and is easy to implement in the active power filter. Then fuzzy logic system is used to approximate unknown nonlinear function to suppress the influence of parameter uncertainty, and the proposed controller with compensation control based on the fuzzy approximation error estimation can overcome the influence of the fuzzy approximation error on the stability of the system, improving the effect of compensation current tracking and strengthening the ability of harmonic suppression. Simulation studies in the MATLAB/Sim Power Systems Toolbox demonstrate that the proposed control methods offer a good behavior in both steady state and transient operation during balanced and unbalanced load compared to traditional backstepping control.

第37届中国控制会议

作者： Shixi Hou Juntao Fei Yundi Chu College of IOT Engineering Hohai University

In this paper, a nonsingular terminal sliding mode control（NTSMC） is proposed for active power filter（APF） to attenuate the effect of unknown external disturbances and modeling uncertainties. Firstly, the dynamic model for APF is build in which both the system parameter variations and external disturbance are considered. Then a nonsingular terminal sliding mode control based on backstepping（NTSMCB） approach is presented for current tracking control system to solve singularity point problem and realize the fast and finite time convergence. The parameters are derived from the Lyapunov stability analysis to guarantee tracking performance and stability of the closed-loop system. Simulation studies in the MATLAB/Sim Power Systems Toolbox demonstrate that the proposed control methods offer a good behavior in both steady state and transient operation compared to traditional sliding mode control.

第30届中国控制与决策会议

作者： Shixi Hou Juntao Fei Yundi Chu jiangsu Key Laboratory of Power Transmission ＆ Distribution Equipment Technology

In this paper, a modified adaptive fuzzy control with approximation-error-adaptive capability（MAFCAEAC） is proposed to improve dynamic performance of three-phase active power filter（APF）. Firstly, the mathematical model of active power filter with parameter perturbation and unknown external disturbance is established. Then based on the direct adaptive fuzzy control structure, the compensation control term based on the fuzzy approximation error is designed to relax the dependence on the assumption that the fuzzy approximation error is square integrable. The adaptive estimation of the fuzzy approximation error is designed to avoid the high gain and chattering problem caused by the previous compensation items. The parameters are derived from the Lyapunov stability analysis to guarantee tracking performance and stability of the closed-loop system. Simulation studies in the MATLAB/SimPower Systems Toolbox demonstrate that the proposed control methods offer a good behavior in both steady state and transient operation during balanced and unbalanced load.

T-S Fuzzy Control with Parameter Estimation for Three-Phase Active Power Filter

T-S Fuzzy Control with Parameter Estimation for Three-Phase ...

第30届中国控制与决策会议

作者： Shixi Hou Juntao Fei Yundi Chu College of IOT Engineering Hohai University

In this paper, active power filter is modeled based on T-S fuzzy theory to reduce the computational burden of the traditional method, and the fuzzy controller is constructed according to the principle of parallel distributed compensation. In view of the fact that T-S model parameters is difficult to obtain and vulnerable to external disturbance and parameter perturbation, an adaptive fuzzy controller with parameter estimation(AFCPE) is designed to ensure parameter estimation error asymptotically converges to zero and improve the reliability of the system and the robustness to parameter variations. The parameters are derived from the Lyapunov stability analysis to guarantee tracking performance and stability of the closed-loop system. Simulation studies in the MATLAB/SimPower Systems Toolbox demonstrate that the proposed control methods offer a good behavior in both steady state and transient operation during balanced and unbalanced load.
