Abstract A control method combined with Sugeno type fuzzy neural network (SFNN) synchronous compensator and complementary sliding mode controller (CSMC) is proposed for position synchronization control problems of dual linear motors servo system in a high precision direct drive gantry position stage. The permanent magnet linear synchronous motor (PMLSM) dynamic model with uncertainties such as parameter variations, external disturbances and friction forces was established, and CSMC is designed by the combination of generalized sliding surface and complementary sliding surface. CSMC can efficiently suppress the influence of uncertainties and weaken the chattering phenomenon in the traditional sliding mode controller (SMC), reduce the tracking errors of the system and achieve high precision position tracking. Meanwhile, SFNN synchronous controller is used to solve the dynamic parameter unmatched problems between two linear motors and the coupling phenomenon. SFNN can make error compensation for each axis, so that it can reduce the position synchronization error and guarantee synchronization control of the system. The experimental results show that the control method can significantly reduce the tracking error and synchronization error of the system, and further improve

摘要 针对高精密直驱龙门定位平台的双直线电机伺服系统的位置同步控制问题,提出一种 Sugeno 型模糊神经网络(SFNN)同步补偿器和互补滑模控制器(CSMC)相结合的控制方法。建立 了含有参数变化、外部扰动和摩擦力等不确定性的永磁直线同步电机(PMLSM)动态模型,采用广 义滑模面和互补滑模面相结合的方式来设计 CSMC。CSMC 可有效抑制参数变化、外部扰动和摩擦 力等不确定性的影响,削弱传统滑模控制器(SMC)存在的抖振现象,减小系统的跟踪误差,实现 高精度位置跟踪。同时,利用 SFNN 同步补偿器解决双直线电机间动态参数不匹配问题及耦合现 象,SFNN 同步补偿器可对每个轴进行误差补偿,从而减小位置同步误差,保证系统实现同步控制。 实验结果表明,该控制方法可明显减小系统的跟踪误差和同步误差,进而改善轮廓加工精度。
