Summary: The paper describes a flatness-based control scheme for the permanent magnet synchronous motor. A hierarchical control is developed and the scheme is shown to be compatible with the flatness properties via a detailed time-scale analysis. The proposed control strategy also achieves copper loss minimization at all operating points. Detailed simulations are presented to illustrate stability and robustness properties of the control scheme.

Summary:The flatness of the mathematical models of the three-phase three-wire and four-wire boost rectifiers is shown. Two trajectory planning algorithms are developed that enable fast voltage restoration after load steps by considering a load estimate. A load observer is suggested. Two tracking controllers are given. Simulations with a switched model show the value of the results
