Abstract :
Microprocessor-based digital control of high-performance AC servomotor drives offers the potential for a flexible and interactive control tool. Typical field oriented control (FOC) servo drives have current loop sampling rates of 5 to 10 kHz. This implies that the controller must process the control algorithms within 100 to 200 mu s. Thus, if complex or novel control methods are to be employed, and if user interaction is required, controllers with high computational power are required. The authors discuss the use of transputers and parallel processing for the implementation of an interactive, high-performance digital controller for a FOC servo drive. Various design issues encountered during the implementation are considered, and the results obtained to date are presented.<>
