一种基于新型滑模趋近律的异步电机调速方法
An Asynchronous Motor Speed Regulation Method Based on a New Sliding Mode Reaching Law
摘要
Abstract
Aiming at the poor robustness and system vibration problem of asynchronous motors under the traditional sliding mode control,a variability coefficient power exponent reaching law(VCPERL)was proposed to dynamically change the control coefficients according to the position of the sliding mode surface,and the sliding mode controller was designed based on this reaching law.Firstly,according to the advantages of quick-power reaching law(QPRL)and the double-power reaching law(DPRL),which have different reaching rates at different positions of the sliding mode surface,meanwhile,the tanh(x)was used to replace the sign(x),and a variable coefficient was introduced into the reaching law.Secondly,the stability of the new reaching law was proved based on theoretical analysis and simulation.Finally,the VCPERL was applied to design the sliding mode controller according to the theory of vector control oriented by rotor magnetic chain and the dynamic mathematical model of asynchronous motor.The simulation results show that compared with the traditional PI control,QPRL and DPRL,VCPERL has strong immunity to load disturbances and fast recovery capability,which can effectively improve the dynamic response performance of the system.关键词
