Switching-Based SVPWM Control for Three-Phase Active Power Filter
Zhang Menghua,Cheng Xingong,Zong Xiju,Zhang Yong 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.11
A switching-based SVPWM control method for three-phase active power filter is proposed in this paper. First, error model of the switched system is established. And then, according to the space voltage vector diagram and three-phase supply voltage waveforms, the supply voltage is divided into six sectors. In each sector, a combination of switching subsystem is set up according to the requirement of quadratic stability condition. Finally, the common Lyapunov function is selected and therefore, the subsystem is determined, which has minimum derivative of Lyapunov function and meets the conditions above. The validity of the proposed control method is proved with Matlab/Simulink and experimental results.

An enhanced coupling PD with sliding mode control method, called ECPD-SMC in short, is presented for double-pendulum overhead crane systems in this paper. The proposed method replaces the PD controller with the equivalent part of traditional SMC method, without any system parameters. TheECPD-SMC algorithm is composed of PD control part and the SMC control part. The SMC part is utilized for constructing the frame of a controller, providing strong robustness with uncertain model, different system parameters, and external disturbances. The PD control part is used to stabilize the control system. Moreover, the coupling behavior between the trolley movement and the payload swing is enhanced, and hence, leads to an improved control performance. As shown by Lyapunov techniques and Schur complement, the proposed ECPD-SMC guarantees asymptotic result even in the presence of uncertainties, including model, system parameters, and various disturbances. Some simulation results are included to demonstrate the correctness and superior control performance of the designed controller.
