模糊PID算法在车载动中通系统的应用

The application of fuzzy-PID algorithm on "Communication in Moving" system

模糊PID控制策略既具有模糊控制灵活而适应性强的优点,又具有PID控制精度高的特点,并且控制方案不需要建立精确的受控对象的数学模型,非常适合作为车辆高速运转时实现动中通方位角稳定的控制策略。介绍了模糊PID控制策略的基本原理,并成功的将它应用于车载动中通伺服系统,保证了动中通的方位角可以在复杂的运动条件下保持稳定,结合俯仰和横滚控制策略实现了该系统在运动中实现稳定通信的设计初衷。

The fuzzy- PID control method is a kind of algorithm which is not only agile and adaptable as fuzzy control but also precise as PID control, and this method does not need to build an accurate mathematical model for the controlled object, so it is the right method that can be used to keep azimuth angle stable for the ＂Communication in Moving＂ system moving in great speed. This paper introduces the basic theory of the fuzzy - PID control method and successfully applies it to the ＂Communication in Moving＂ servo system, then guarantees the stable of the ＂communication in Moving＂ system＇s azimuth angle in complicated moving status, combined with elevate angle and roll angle control method to realize the design object of communication in moving.
