摘要
为提高机电天线伺服系统性能,针对力矩电机直接驱动式天线伺服系统预定回路的特性,应用最优控制理论分别设计LQG控制器和LQG/LTR控制器,并研究其应用效果。在单输入单输出系统中,LQG/LTR控制器可以直接替换PID控制器的位置。仿真结果表明,采用LQG/LTR控制器可使系统具有良好的鲁棒性。
In order to improve the performance of electromechanical antenna servo sys- tem, the LQG and LQG/LTR controllers are separately designed based on optimal control theory for the preset loop of an antenna servo system driven directly by torque motor. The application effect the two controllers above was researched as well. In single input and single output system, the PID controller can be directly replaced by LQG/LTR controller. The simulation result shows that the system has good robustness.
