Design of Weapon Depth Control System Based on Switching Grey Prediction Fuzzy PID Controller

分析扫雷梨自动定深系统,选用模糊PID作为主控制器,采用变步长灰色预测模糊PID控制器去实现某武器扫雷犁自动定深系统的控制。通过对系统进行建模检验该控制器的控制效果。采用联合仿真的方式实现了用Simulink中的控制器去控制AMEsim中的电液伺服系统。仿真结果表明:变步长灰色预测模糊控制器能够有效抑制系统非线性特征,鲁棒性较好,满足系统控制精度要求。

This paper analyses the weapon depth control system, chooses the fuzzy PID as the main controller and used the switc- hing grey prediction fuzzy PID controller to control the weapon depth system. It also establishes the model of the depth control sys- tem, tests its control effect and uses simulink controller in the combination simulation method to control the hydraulic system in AMEsIm. The result shows that, the switching grey prediction fuzzy PID controller can be used to overcome the nonlinear characteristics of the system better. It is of more outstanding robustness and higher control accuracy.
