摘要
传统PID控制器因结构简单、易于实现而在控制系统中得到了广泛运用,但往往因实际系统中的非线性因素影响而不得不采用变结构、变参数等手段来提高实际控制效果,而模糊控制对非线性因素的影响却能明显改善系统控制品质。文中主要研究了模糊自整定PID控制方法在雷达伺服系统中的应用,并在实际系统中进行了实验验证。仿真结果表明该方法能明显提高系统控制品质,具有一定的工程推广价值。
Ahhough PID control is widely used, it is linear at working point. It can＇t ensure dynamic quality when away from working point, while fuzzy self-tuning PID control can. In this paper, we research on application of fuzzy self-tuning pid control to radar servo system. Firstly we study the fuzzy self-tuning PID ontrol and then we verified in a practical servo drive system model. It proved that the fuzzy self-tuning pid control can be applied to the radar servo system with precision and flexibility.
