Research on Control of Grid Side PWM Converter of Doubly Fed Wind Generator Based on Sliding Mode Variable Structure
摘要
Abstract
In order to improve the control performance of double fed wind power generation controller, aiming at the drawbacks of traditional PI control,tracking error,slow steady state is not good, according to the mathematical model of doubly fed wind power generation controller,a variable structure control strategy is used to make a systematic study of the grid side PWM converter with sliding mode control based on exponential approach law,and it is compared with the traditional PI control strategy.The simulation results show that the variable structure control strategy not only simplifies the structure of sliding mode control based on exponential approach law,and improve system response speed,which has a certain validity and reliability for the stability of the DC bus voltage.关键词
