炮管俯仰系统建模及油液污染影响控制仿真

非平衡炮管俯仰系统控制的关键是如何克服变化非平衡力矩、油液污染造成内部参数改变等扰动的影响。为实现其高精度控制,给出了一种基于模糊PID理论设计的控制器,采用集中参数法建立各组件数学模型并联立得到系统整体模型,进而搭建Matlab/Simulink仿真模型,应用传统PID控制器与模糊PID控制器进行驱动腔的控制。对比仿真结果表明,模糊PID控制可有效提高系统控制精度至0.1mil,且响应速度得到了一定改善。证实了PID控制结构简单却不能在线调整参数,模糊PID控制因具有较强的鲁棒性而容易获得更好的控制效果。

Modeling and Oil Contaminated Influence Control Simulation of Barrel Pitching System

The key of the unbalanced barrel pitching system control is how to overcome the effects of disturbances such as the changing non-equilibrium torque and the internal parameters’change caused by oil contamination.In or-der to realize its high-precision control,a controller designed based on fuzzy PID theory is presented.The lumped parameter method was used to establish the mathematical model of each component and to obtain the overall model of the system,then the Matlab/Simulink simulation model was built,and the traditional PID controller and the fuzzy PID controller were applied to control the drive cavity.The comparison simulation results show the fuzzy PID control can effectively improve the control accuracy to 0.1 mil,and the response speed is also improved.It is proved the structure of PID control is simple but the parameters cannot be adjusted online.It is easy for the fuzzy PID control to obtain better control effect because of its strong robustness.
