Application of PID algorithm in carborne communication in moving satellite communication system

PID控制策略算法简单、鲁棒性好、可靠性高,此外,PID控制方案并不需要建立精确的受控对象的教学模型,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PID控制策略的基本原理,并成功的把它应用于动中通伺服系统,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通信的设计初衷。

The PID control method is a kind of algorithm with the advantage of simple, robust, high dependability, and this method does not need to build an accurate mathematical model for the controlled object, so this is the right method which can be used to keep azimuth angle stable for the 'Communication in Moving' system moving in great speed. This paper introduce the basic theory of the PID control method, the paper successfully apply the method to the 'Communication in Moving' servo system, and guarantee the stable of the 'Communication in Moving' system's azimuth angle in complicate moving status, combined with elevate angle and roll angle control method realized the design object of communication in moving.
