摘　　要：文章针对高速LED焊线机研发中存在的高速运动过程精密定位难题,在原位力混合控制系统上提出一种基于模糊PID控制的改进控制算法。该算法作用于运动系统切换之后的速度环路控制,有效调节控制系统的超调量。基于经验法获取的初始PID参数,该算法通过模糊控制方法在线调整运动切换后控制系统的PID参数,使之快速适应系统的变化。该算法的仿真分析结果表明,改进的模糊PID控制算法具有超调量小、调节时间短的特点,能快速调整高速运动系统的冲击,有效改善高速运动控制系统的性能。On the in situ force hybrid control system,an improved algorithm based on fuzzy PID control is proposed in this paper aiming at the precision positioning problem existing in the high speed LED wire bonding machine development. It acts on the speed loop control after the movement system was switched,adjusting effectively the overshoot of control system. Based on the initial PID parameters acquired by empirical method,it adjusts online the PID parameters of control system by the fuzzy control method,making it adjust rapidly to the system change. The simulation result of the algorithm indicates that the fuzzy PID control algorithm proposed possess the characters of lowovershoot and short adjustment time,thus is able to adjust rapidly to the shock and improve effectively the performance of high speed movement control system.
