摘　　要：针对飞机起落架舱的制孔工艺,提高制孔质量与效率,设计了一种面向飞机起落架舱的自动化制孔系统。该系统的机械执行机构由伺服电机、丝杆螺母机构、滚珠导轨来实现的。由PLC控制器作为系统的中央控制中心,协调控制各机构的运动。为了提高控制性能,采用分数阶PID控制。分数阶PID控制器较传统的PID控制多引入了2个参数,进而可以大大提高控制系统系统的鲁棒性。因为分数阶PID控制器的控制性能取决于参数的选择,所以利用粒子群算法以获得较佳的参数设置。In order to improve the drilling quality and efficiency of the wheel well of aircraft,an automatic drilling system is designed.Its mechanical actuator is made of servo motor,feed screw and ball guide rail.PLC controller is used as the controlling center,which coordinates and controls the movement of all units.In order for better controlling performance,a fractional order PID controller is adopted.Compared with the traditional PID controller,two more parameters are introduced into the fractional order controller,so the controlling of the fractional order controller is much more robust.Since its controlling performance is dependent on its parameters,PSO is used to search for the better parameter combination.
