Quasi-continuous implementation of structural nonlinear controller based on direct-decoupling for Permanent Magnet Synchronous Motor

The paper proposes a quasi-continuous implementation of a continuous control design for a Permanent Magnet Synchronous Motor (PMSM). Based on an idea of exact linearization, the authors present a direct-decoupling structure for the PMSM. The main focus of our research is to develop nonlinear control algorithms for the PMSM, which are highly applicable for real-time digital implementation. The experimental results show the effectiveness of the proposed quasi-continuous implementation.
