Abstract :
The paper deals with a Direct Predictive Control (DPC) algorithm applied to the speed and current control of a permanent magnet synchronous motor (PMSM) drive. The main contribution is a comprehensive and detailed description of the hierarchical structure, which yields a choice of the control input voltage that combines dynamic performances with the efficiency care. The selection principle is particularly simple and intuitive, and thus it is suitable for direct implementation in standard drives. The paper also gives some practical hints for the implementation. Simulation and experimental results confirm the validity of the design procedure and the potentiality of the proposed technique.
