Design, simulation, and testing of a field-oriented ac servo-drive using a TM5 32010 signal processor
Abstract
The design, realization and testing of a servo drive with an asynchronous machine (an ac servo drive) were studied. The asynchronous machine is described by a mathematical model using space vectors. Based on this model, a digital field-oriented speed control was designed using an ideal current source. A characteristic property of this control scheme is that only machine parameter (the rotor time constant) has to be known. The motor model and speed control were simulated with varying parameters such as calculation interval, sampling time and rotor time constant. The speed control was realized as a digital control system with a signal processor operating at a 2 KHz sampling frequency. Test results show that the designed speed control has stable and robust characteristics, and can thus be used in a cascade control of a servo drive.
