摘　　要：由于PID控制算法简单,便于工程实现,传统上雷达转台多采用PID控制。但是雷达转台是非线性时变系统,制约了基于准确线性数学模型的PID控制的控制品质。文中提出了转台位置环采用神经网络控制,速度环采用传统PI控制的复合控制方式,一方面采用复合控制模式可以减少控制系统的运算量,便于工程实现,另一方面位置环采用神经网络控制可以提高控制系统的鲁棒性,提高雷达转台的控制品质。最后对复合控制方式进行了仿真验证,仿真结果表明控制方法性能良好。Because of easy realization,the radar turntable adopts P1D control traditionally.However,the radar turntable is a nonlinear and time-varying system,which restricts the control quality of PID control based on accurate linear mathematical model.This paper presents a compound control mode,which adopts neural network（NN） control in position loop,and PI control in speed loop.On one hand,the compound control mode can reduce the computation of the control system,easy to realize in engineering.On the other hand,the position loop based on NN control can improve the robustness of the control system and improve the control quality of radar turntable.The simulation of the compound control mode is made and the simulation results show that the control method has good performance.
