摘　　要：针对不平衡力矩对雷达伺服系统的影响,提出了一种基于转矩前馈补偿的自抗扰控制方法。该控制方法在速度环中采用自抗扰控制器代替传统的比例积分微分(PID)控制器,以提高系统的鲁棒性能;同时,采用了降阶转矩观测器来实时估计负载转矩,并将观测值补偿到电流环控制器,实现电机对负载扰动的快速响应。仿真和实验结果表明,该控制方法有效地抑制了不平衡力矩扰动的影响,提高了系统的鲁棒性能。Aiming at the unbalanced torque in the radar servo system,an active disturbance rejection control(ADRC)method is proposed based on load torque feed-forward compensation.The ADRC technology is applied to the speed loop control instead of traditional proportion integration differentiation(PID)controller in order to improve the robustness of the control system.Meanwhile,reduced order load torque observer is designed to estimate the load torque,and the observed value is used for compensation of the current loop controller to realize quick response to load disturbance.The simulation and experiment results show that the proposed control strategy can effectively suppress the disturbance of the unbalanced torque and improve the robustness of the control system.
