IDA-PBC under sampling for torque control of PMSM

摘要

A nonlinear passivity-based control can be suitably used to achieve stability of a permanent magnet synchronous machine (PMSM). Nevertheless, passivity properties are usually lost when such a controller is implemented in a sampled-data context and, as a consequence, stabilization objectives are degraded. This paper proposes a direct sampled-data control strategy based on the IDA-PBC techniques, in order to keep the same performances with a higher sampling period. Therefore, this type of controller is able to be implemented in a low-performance DSP.
