The Research Of Switched Reluctance Motor Control System

Switched Reluctance Motor(SRM) is a new type of controllable timing-driving system rising in the 1980's of last century.it has super-excellent quality and wide application.it develops with the progress of micro-electronics technology,,control technology ,power electric and modern computer technology.it has the traits of simple structure, high dependability, flexible control and high efficiency.it has been used in several industry department and has a nicer future. It is recognized to has the most potential development in the field of dynamoelectric vehicle driving by international dynamoelectric vehicle science and technology organization.Dissertation researched on the switched reluctance motor control system which takes Intel 80C196KC MCU as the control core. Designing a control scheme based on position sensor.Dissertation explains the theory and characteristices of switched reluctance motor based on its idealy linear math mode. Analyseing and researching on control characteristic,control parameters,control strategy and their relationship, thesis designed hardware circuit and software of control system based on the strategy.Dissertation discussed the transform function of system and illustrates it is essential to chang parameters in the PID control arithmetic, estimating parameters for the digital PID controller primarily, dissertation also researched on the exciting and protection of IGBT. Concluding an utility method of calculating the parameters of protection net of IGBT through theory deducing.Dissertation researched and designed the CAN bus interface of switched reluctance motor system, Emphasis has been put on the data disposal method of avoiding data overrun fault.
