Control of a nonlinear magnetic levitation system by using constraint generalized model predictive control

Abstract

In this paper, we designed generalized model predictive control for linearized magnetic levitation system and applied to the nonlinear system. The proposed control strategy is guarantee the stability of the open loop unstable system and tracking the desired values of the state variables with the stabilizing constraints. The simulation results show that the tracking performance and effectiveness of generalized predictive control strategy. Furthermore, robustness with respect to mismatch between model/process with changes in the parameters of the system are investigated.
