摘要:
 在船载卫星通信系统中，最重要的问题就是利用方位、俯仰、横摇的角度误差值控制直流电机实时调整天线姿态，使天线波束中心始终准确地对准卫星。直流电机控制算法的优劣将直接影响到船载卫星通信系统的工作性能，因此对船载卫星通信系统中控制算法的研究就显得非常重要。 PID算法原理简单，适应性强，鲁棒性好，非常适合应用于船载卫星通信系统；但它也容易出现积分饱和、抗干扰性差的问题。文中基于上述问题，提出积分分离、积分限幅、不完全积分和不完全微分的改进型PID算法，它不但可以防止产生太大超调，而且加快了响应速度，提高了控制精度和抗干扰能力。
Abstract:
 In shipborne satellite communications system,how to use azimuth,pitch,roll angle error value of DC motors to adjust the an-tenna stance in order to achieve real-time antenna pointing stability is the most important problem. The algorithm of DC motors’ control will directly affect the work performance of the communication system,so the study of its control algorithm becomes very important. PID algorithm is simple,adaptable and robust,which is very suitable for shipborne satellite communications system. However,the PID algo-rithm is prone to integration saturation and weak immunity situation. Based on the above-described problems,propose some improved al-gorithms,including integral separation,integral limit,incomplete integration and incomplete differential. The improved algorithms can not only prevent too much overshoot,but also accelerate response speed,improving control accuracy and immunity performance.
