基于单参数模糊PID的水下发射控制系统

Based on Single Parameter Fuzzy—PID Control Of Control System Of Underwater Shooting Equipment

水下发射系统在工作过程中,由于受到负载转动惯量的变化、水阻力矩的影响,使系统的参数发生变化。应用常规的PID控制,难以获得良好的动、静态性能;采用单参数模糊PID控制算法,只须调整α参数即可实现对PID三个参数的调整,经实验证明该方法简单,同时对抑制干扰、消除负载转矩变化的影响具有明显的效果。

In the process of operation, the parameter of the system will change constantly because of the outside influence mainly including the variation of load moment of interior, the effect of interference torque etc. And it is difficult to obtain the better dynamic quality if the routine PID control is used only. Applying the Fuzzy--PID control with single parameter can regulate three parameters through changing αfunction only. As proved through experiments, this methodology is very efficient to restrain interference and get rid of the effect of the load torque variation.
