| 摘 要： | 在传统的直接转矩控制(DTC)系统中,速度控制通常采用PI控制器,而PI控制器必须依赖被控对象的数学模型,特别是在低速范围内不能达到令人满意的控制效果.将一种非线性控制器——自抗扰控制器(ADRC)引入直接转矩控制系统,以改善动态性能,并结合转矩控制系统提出了自抗扰控制器的参数整定方法,同时针对系统的抗扰性能进行了仿真分析.仿真结果表明,采用ADRC的转矩控制系统抗扰性能有显著提高.

| Abstract: | In traditional direct torque control(DTC),speed regulator is widely based on conventional PI controller,which has to depend on precise math model of the subject.However,PI controller cannot easily achieve swift response,small overshooting and fine speed control precision,especially in low speed range.This paper introduces a nonlinear control technology-auto disturbance rejection controller(ADRC) to DTC system,and proposes parameter design method of ADRC in DTC.The principal block diagram is presented.Simulation studies have been carried out for the proposed method;and the results are compared with DTC using PI controller.The simulation results show that the dynamic performances have an improvement by using ADRC. |
