Modeling of One-loop Flatness-Based Control with State Observer-Based Parameter Estimation for PMSM Drive

One-loop flatness-based control modeling with a nonlinear state observer is proposed in this paper to enhance the dynamic response of the PMSM control system. And also the issues in the case of the command saturation are taken into account to prevent the system from becoming uncontrollable. Simulation and experimental result are performed to validate the proposed methodology.
