自适应逆控制策略在IC材料切片设备中的应用

摘要

Aiming at the existed following error and control precision problem of numerical PID control system in high speed synchronous servo control system, a set of adaptive inverse control strategy was put forward. Using host motor as reference model and LMS adaptive control algorithms adjusting controller, the proposed method made supply motor have approximate dynamical property with host motor. The simulation results and product detecting results demonstrate mat the proposed system can effectively reduce the following error and increase the precision of control system.%针对数字PID控制系统在高速同步伺服控制系统应用中存在的跟随误差和控制精度问题,提出了一种自适应逆控制策略,该方法以主电机为参考模型,通过LMS自适应控制算法调整控制器,使放线电机与主电机具有类似的动态特性.仿真结果与产品的检测结果表明系统能有效减小随动误差,提高控制系统的精度.
