Research on Generalized Predictive Control of Hybrid Magnetic Bearing System

A generalized predictive control technique for hybrid magnetic bearings is put forth in this study. Firstly, a nonlinear model is established for the radial freedom of hybrid magnetic bearing, and is then linearized through small perturbation method at the equilibrium point, it is used to develop a generalized predictive controller. Then, the technique’s results proposed on the radial freedom floating control is analyzed together with the interference suppression ability, meanwhile the effect of main control parameters and the performance of the system are analyzed and compared, which contrast the conventional PID control approach. The simulation’s findings indicate that the generalized predictive control system presented has a better dynamic performance and robustness.
