摘要
针对当前交流异步电动机矢量控制存在综合性能不理想的问题,通过设计基于积分滑模面函数的滑模控制器(SMC),建立了基于滑模控制、PI控制技术相结合的异步电动机矢量控制仿真模型。仿真测试表明:在有内外扰动的情况下,通过配置合适的相关控制参数,基于SMC-PI的综合控制模型能够使异步电动机转子的磁链和转速脉动幅度保持在很低的水平,能让电机对扰动快速作出反应,并保持很高的稳定性和鲁棒性。
Aiming at the problem that the comprehensive performance of vector control of AC asynchronous motor is not ideal at present,a simulation model of vector control of asynchronous motor based on the combination of sliding mode control and PI control technology is established by designing a sliding mode controller(SMC)based on integral sliding mode surface function.The simulation test shows that the integrated control model based on SMC-PI can keep the flux linkage and speed fluctuation amplitude of the asynchronous motor rotor at a very low level by configuring appropriate relevant control parameters in the case of internal and external disturbances and enable the motor to respond quickly to the disturbances and maintain high stability and robustness.
