摘要
为了解决永磁同步电机(PMSM)调速系统突加负载或负载扰动时控制性能差的问题,提出用自抗扰控制技术设计PMSM控制方案.将负载突变和负载扰动归为未知扰动,用自抗扰控制器进行估计、补偿和控制.仿真结果表明,该方法能够提高系统的响应速度,减小稳态误差且无超调,能有效地抑制负载变化对转速的影响.
in the PMSM speed-regulation system, the control performance will become worse when a load is added suddenly or some disturbances existing in the load. In order to solve this problem, a new control scheme which was designed by a technique of ADRC was represent in this paper. The load-mutation and load-disturbance were all contributed to an unknown disturbance and ADRC is used for system estimation, compensation and control. Simulations showed that this method can not only quicken the speed-response of system without over-shooting, but also reduce the error of the steady state, further more it is more robust to the load-mutation and load-disturbance.
