摘要
永磁同步电机(PMSM)在工业领域的应用十分广泛。针对PI控制器无法解决快速性和稳定性之间的矛盾且抗扰动能力弱的问题,在PMSM矢量控制系统的转速环中用自抗扰控制(ADRC)控制器代替PI控制器。利用Simulink分别对基于ADRC和基于PI控制的PMSM矢量控制系统进行仿真,对2种策略的控制效果进行对比。利用dSPACE试验平台对仿真结果进行了初步的验证。结果表明,ADRC有效地抑制了扰动,转速调节快速且无超调,提高了系统的控制性能。
Permanent magnet synchronous motor(PMSM)is widely used in the industrial field.PI controller of PMSM cannot deal with the contradiction between fastness and stability,and the anti-disturbance ability is weak.In order to solve these problems,the active disturbance rejection controller(ADRC)is used instead of PI controller in the speed loop of PMSM vector control system.Simulink is used to simulate the vector control system of PMSM based on ADRC and PI control respectively,and the control performances of the two strategies are compared.Then,the dSPACE experimental platform is used to verify the simulation results.The results show that the ADRC effectively suppresses the disturbance,the speed is adjusted quickly without overshoot,and the control performance of the system is improved.
