Fractional-Order Identification And Control Of Permanent Magnet Ac Servo System

AC servo systems are widely used in traditional industries, high-tech fields, etc. In order to meet the design requirements of high-performance systems, this paper constructs a fractional-order model that more accurately describes the characteristics of the object, and obtains the model parameters through the identification algorithm. On this basis, the corresponding fractional-order PI controller is designed to further improve the performance. Finally, the simulation and experiments show that the fractional-order model can more accurately characterize the servo system. Moreover, the fractional-order PI controller-can effectively improve the dynamic and inti-disturbance performance of the servo system.
