Adaptive Fuzzy Sliding Mode Variable Structure Control for AC Servo Systems

研究并设计了应用在交流伺服系统中的自适应模糊变结构控制器。该控制器结合自适应控制、模糊控制和变结构控制等理论的优点,不仅加快了交流伺服系统的响应速度,提高了控制精度,增强了抗干扰能力,而且避免了常规矢量控制方法复杂的坐标变换,实现简单。实验结果验证了该控制方法的可行性和有效性。

An adaptive fuzzy variable structure controller for AC servo systems is designed,which combines the merits of adaptive algorithm ,fuzzy logic control and sliding mode variable structure theory.It is realized simply because complex coordinate transformation is avoided.AC servo systems controlled by the proposed method has speedy response,high accuracy and strong robustness against parameter variations and load disturbances.The experimental results indicate that the proposed control method is feasible and effective.
