Research on the Application of Fuzzy PID Compound Control in the Load Simulator of the Servo System for a Weapon Equipment

为提高某武器装备随动控制系统的加载精度,针对在力矩加载时,随动负载模拟器将会受到齿轮空回、间隙、局部摩擦、弹塑性变形和干扰力矩负载扰动的影响,对负载模拟器的系统组成、工作原理和数学模型进行分析,再将输出力矩传递函数进行推导,并将灰预测模糊应用于控制器中。系统仿真结果表明:该复合型控制策略能够具备速度响应快、跟踪准确、无超调等特性,具有较强的鲁棒性,优于传统PID控制,能够满足武器装备高精度的随动控制跟踪要求。

In order to improve the loading accuracy of the servo control system of a weapon equipment,the system composition,working principle and mathematical model of the load simulator were analyzed,and then the output torque transfer function was deduced,and the grey prediction was made fuzzy measurement was applied to the controller.The simulation results show that the composite control strategy has the characteristics of fast response,accurate tracking,no overshoot,strong robustness,superior to the traditional PID control,and can meet the tracking requirements of high-precision follow-up control for weapon equipment.
