基于非线性积分滑模变结构控制三相VSR的研究
Study of three-phase voltage-source PWM rectifier based on nonlinear integrator sliding mode
摘要
Abstract
A nonlinear integrator sliding mode of variable structure control strategy,based on traditional integrator sliding mode,was applied in three-phase voltage-source PWM rectifier (VSR) to improve the robustness of parameter uncertainties load disturbance.And this control strategy contains error and error integral term and makes that three-phase voltage-source PWM rectifier not minimize chattering and steady state error but has excellent robustness.Then,integral term is weakened to avoid large overshoots and reduce the state error,which can lead to integral saturation effect (windup).At the same time,an exponential reaching law which can further suppress chatting and improve the reaching speed is presented.The three-phase voltage-source PWM rectifier based on nonlinear integrator sliding mode variable structure control strategy is superior to traditional integrator sliding mode control and the conventional double-loop PI control system in low overshoots,anti-interference and speed tracking by MATLAB simulation.关键词
