Design of an open architecture structure for implementation of predictive controllers for motor drives

Several predictive algorithms have been proposed with very nice results obtained on a benchmark dedicated to motor drives control for machine tools applications. However, due to the rapid innovation in the development of microprocessors and communication technology, it becomes more and more necessary to generate software in a hardware-independent way. The consequence of this requirement is the introduction of a link between application software and hardware, in an open architecture oriented structure. This paper presents an open architecture structure of motor drives control with a particular application to an axis induction machine control, showing the connection between the motor (including load, PWM inverter, current sensors, incremental encoders) and the software developments for the end users (automatic design of the tuning parameters and controller) through a DSP based implementation of the real time part.
