摘要
针对光电跟踪伺服系统提出了一种新的控制算法。该算法将模糊控制与经典滞后超前控制结合起来,在保持原有系统精度的前提下,使光电跟踪伺服系统的动态性能得到了极大的改善。仿真结果表明,采用该算法后系统的 ts<0.1s, σ=0。采用经典的描述函数法对模糊控制系统进行了稳定性分析,说明系统是稳定的。
A new algorithm was put forward for an opto-electronic tracking servo system. The algorithm combines a new fuzzy control algorithm with classic control algorithm and greatly improves the dynamic performance of the opto-electronic tracking servo system while keeping the systematic precision of the original system .The simulation results show that the adjustment time is ts<0.1s and overshoot is σ=0. Simultaneously, the stability analysis by means of classic function description of the fuzzy control system demonstrates that the system is stable.
