A geometric approach for controlling an electromagnetic actuator with the help of a linear Model Predictive Control

In permanent magnetic machines the nonlinearity due to the quadratic terms of the current makes difficulties in the control system. In order to cancel the nonlinearity, a strategy based on a pre-compensation action, which is conceived through two input partition matrices is presented. After canceling the nonlinearity, a Model Predictive Control is used to obtain a positioning of the actuator. Simulation results are reported to validate the proposed technique.
