摘要
结合自抗扰控制器(ADRC)控制机理和永磁同步电机(PMSM)数学模型,设计了基于ADRC的转速环控制器和电流环控制器代替传统的PID控制器形成新的伺服系统。ADRC使整个系统抗负载扰动能力得到较大改善,提高了系统的鲁棒性和控制精度,有效地抑制了电流谐波的产生。仿真结果表明,与传统PID控制的伺服系统相比,该系统在负载转矩变化时响应速度快、超调量小、控制精度高,在电机内部参数发生变化时该系统调节几乎不受影响,具有较强的鲁棒性。
By combining the control mechanism of ADRC with the mathematical model of PMSM, a new servo system based on ADRC current loop controller and speed loop controller was designed to replace the traditional PID controller. The ADRC controller improved the anti-load disturbance ability of the system, improved the robustness and control accuracy of the system, and effectively suppressesed the generation of current harmonics. The simulation results showed that compared with the traditional PID control servo system, the system had fast response speed, small overshoot and high control accuracy when the load torque changed. When the parameters of the motor changed, the system regulation was almost unaffected and had strong robustness.
