Robust Position Controller for a Permanent Magnet Synchronous Actuator

Problem statement: The present study investigated with the application of a robust control scheme to improve the performance of a simplified indirect field oriented for small power surface mounted Permanent Magnet (PM) synchronous actuators. Approach: The suggested model was implemented using a simplified state feedback with no need to measure the current values to compute the control algorithm. Results: The current values were estimated by an accurate prediction model estimated from real input/output data. The suggested control scheme was enabling the possibility to perform a position controller by using only a position sensor. Conclusion: The performance of the controller was evaluated and validated by digital simulation using SIMNON package and the usefulness of the suggested method was proved.
