Dsp-based Speed Motor Controller Research

With the development of Electric Power and Electronic technology, Micro Electric technology, special integrated chips and the theory of Automatic control, the application of Motor control theory is widely extended in practice. Motor controller is gradually improving into Digital controller with optimal capacity and simple structure.In order to get the Real-time Motor controller with wide speed scope, high precision and large ability, this paper has used the special Digital Signal Processor (DSP) made in Texas Instrument for Motor control to design and finish the speed adjustable Motor controller, analyzed the control methods and discussed the application in the fields of position testing, drive and power inverter circuit, completed related hardware testing and tested its functions.The controller this paper developed has small volume, different capabilities and is easy to be united. It fits to the circumstance which is required high accuracy, high precision and wide speed adjusting scope. This paper has built up some hardware bases for the later designation.
