摘要
异步电动机矢量控制系统的转子磁链观测精度会因电机运行过程中的参数变化而降低,这是限制矢量控制系统性能的一个主要问题。使用一种不依赖对象数学模型的强鲁棒性控制器——自抗扰控制器(ADRC)来解决以上问题,给出了双闭环系统ADRC转速及磁链控制器的设计方法,揭示了基于ADRC的系统的抗扰性能和鲁棒性优于PI控制系统的本质原因。
The precision of the rotor flux observation is sensitive to the variations of system parameters when field oriented control of induction motor is implemented. This is the main reason that limits the performance of the vector control system. An unique way of problem solving is proposed that of using auto disturbance rejection controller with strong robustness to minimize the effects of system parameter variations, The design method of ADRC speed regulator and rotor flux regulator of the system is given.
