DSP controller for a permanent magnet synchronous motor drive

The drives industry is steadily moving towards digital implementation of controllers for variable speed drives. This paper discusses the implementation of a DSP controller for controlling a permanent magnet synchronous motor (PMSM). It discusses the theory of operation of a PMSM drive and shows how a DSP controller has been designed to perform the vector and current control functions. The design criteria is presented and advantages and disadvantages of the DSP selected to perform the vector and current control functions is discussed. The techniques used in software development are also discussed.<
