Abstract :
In the last decade and particularly the last several years, multirate control has been an area of active research. Concurrent with the development of multirate strategies, there have been increasing applications of digital signal processors in high speed control. The paper presents the design and implementation of a new multirate controller for a servo drive. The item controller is first designed using MATLAB with SIMULINK. It is then implemented using the Analog Device digital signal processor ADSP-21020. The controller is shown to be superior to a conventional digital LQG controller
