The Sliding Variable Structure Control of Mixed Magnetic Bearing System

摘要：

Mixed magnetic bearing system (MMBS) has a complex non-linear. Firstly, this paper analyzes MMBS according to the principle and a mathematical model is established. And then a sliding mode variable structure control (SMVSC) method is presented, which bases on nonlinear system. Compared with the traditional PID control method, SMVSC has good stability and robustness. At the same time, it can rapidly achieve system balance within a short time and has a strong inhibitory effect to interfering signals. Simulation results show the effectiveness and practicability of the algorithm.
