摘要
为了提高机载光电跟踪伺服控制系统的控制性能,提出了一种模糊自整定PID控制算法.该算法将模糊控制和经典PID控制相结合,在保持原有系统精度的前提下,使机载光电跟踪伺服控制系统的动态性能得到了改善.仿真结果表明,该控制算法较之经典PID控制算法具有响应快、超调量小、抗干扰能力强等优点,对机载光电跟踪伺服控制系统具有较好的控制能力.
In order to improve the control performance of airborne electro-optical pointing and tracking systems,a new algorithm,fuzzy self-adjusting PID control,is presented.The algorithm combines a new fuzzy control algorithm with classic PID control algorithm and greatly improves the dynamic performance of the airborne electro-optical pointing and tracking systems while keeping the systematic precision of the original system.The simulation results indicate that the algorithm is fast in response,low in overshoot and robust in disturbance and has preferable control capability than classic PID control algorithm.
