中文摘要:

      文中为了克服天线座系统中存在的由关节摩擦、传动齿隙等引起的内部扰动以及由外界环境变化引起的外部扰动，实现并联驱动式新体制雷达天线座的高精度运动控制，设计基于自抗扰控制（Active Disturbance Rejection Control, ADRC）的新体制雷达天线座控制系统；针对ADRC参数众多且难以快速整定的问题，将ADRC参数整定转化为优化问题，并采用多策略混合粒子群优化（Multi-strategy Hybrid Particle Swarm Optimization, MSH-PSO）算法对自抗扰控制器参数进行优化整定。电机控制实验和天线阵面运动控制实验结果表明：基于自抗扰控制的控制系统在实现新体制雷达天线座运动控制时具有很好的稳定性和高指向精度。

英文摘要:

      In order to overcome the internal disturbance caused by joint friction, transmission backlash and external disturbance caused by external environment change, and realize the high-precision motion control of the new parallel drive radar antenna pedestal, a new radar antenna pedestal control system based on active disturbance rejection control (ADRC) is designed. To solve the problem that there are many ADRC parameters and they are difficult to adjust quickly, the ADRC parameter tuning is transformed into optimization, and multi-strategy hybrid particle swarm optimization (MSH-PSO) is used to optimize the parameters of ADRC controller. The results of motor control experiment and antenna array motion control experiment show that the control system based on active disturbance rejection control has good stability and high pointing accuracy when realizing the motion control of the new radar antenna pedestal.
