摘　　要：针对风洞试验段搓板机构存在的"动板"错动困难、定位精度不高、重复性较差和不利于人员现场检查动板错动情况等问题,研制一种通用运动自动控制器+交流伺服系统的控制系统。按照技术指标和要求,控制系统将驱动电机更新为交流伺服电机,位置控制采用UMAC的速度/加速度前馈PID控制算法、同步控制采用交叉耦合同步策略。结果表明:该系统稳定可靠,正反向定位精度优于0.5 mm,同组中2台电机的同步效果良好,达到设计指标要求,并已成功应用于风洞试验段的流场调试。To eliminate wind tunnel porosity adjusting mechanism-moving plate’s “movable plate” running difficulty, low position accuracy, low repeatability and unfavorable inspector’s inspection problems, the control system was developed based on the combination of universal motion and automation controller （UMAC） and AC servo motors. According to specifications and requirements, the control system upgraded drive motors to AC servo motors, which position control applied the control algorithm of PID ＋ velocity/acceleration feed forward ＋ notch filter, synchronization control used the cross-coupling synchronization control strategy. The application showed that the system is stable and reliable, positive and negative positioning accuracy is better than 0.5 mm, synchronization of 2 motors in same group is good, design specifications has been satisfied and successfully applied to flow field debugging of wind tunnel test section.
