作为地空通信测控系统伺服分系统的核心部件,数字控制器需要满足不同角度范围的跟踪需求.针对小角度范围,采用自适应二阶无静差 PID控制器实现;针对大角度范围,采用开关控制实现;并从方位支路和俯仰支路2个方面讨论了系统跟踪误差.分析结果表明:该控制器实现了对速度输入量的误差跟踪和快速最优控制,并保证天线的稳态性能和动态性能,足以满足系统跟踪的精度需求.

As the core component for the servo subsystem of the air-ground communication monitoring and control system, the digital controller needs to meet the needs of different angles range tracking. Use adaptive second-order non-static error of PID controller for the small angle range, and switch control for large angle range. The system error tracking is also discussed both from orientation slip and pitch slip. The analysis results show that the controller achieves error tracking and fast optimal control, and ensure the steady-state performance and dynamic performance of the antenna. In summary, the tracking accuracy of the system requirements is satisfied.
