摘要
在采用定子磁场定向的感应电机调速系统中,为提高控制系统的鲁棒性,抑制负载扰动的影响,提出了用自抗扰控制器来控制系统的转速环的设计方案,将负载扰动归到未知扰动中,用自抗扰控制来进行估计、补偿和控制。数字仿真证实了自抗扰控制器不仅能够提高系统的动、静态性能,而且能有效地抑制负载扰动,对负载扰动有较好的鲁棒性。
In order to improve system robustness and restrain the result of load-disturbance, active disturbance rejection controller is presents, which is applied in speed loop of the speed controller of AC drive system based on stator-flux-oriented. The load disturbance what is belonged to the uncertain disturbance is estimated, compensated, controlled by ADRC. Simulation results show. This method not only has better dynamic performance and higher steady performance but also has better robust property to load disturbance.
