Switched Reluctance Motor Drive system(SRD for short) is a kind of new-style drive system,it have already become a hot research subject.This paper uses an 0.75KW four-phase 8/6 pole SRM as the research object,completes the research and design of the drive system based on the SRM's ideal linear model. The paper firstly introduces the research of SRD both at home and abroad nowadays,then describes the basic structure and the characteristics of the system.Based on its ideal linear model,the paper analysed the relation of the motor's flux,current,torque and other parameters.The paper summed up the impact factors of each parameter,and finally,lodges a method of control for this drive system in practice. At the aspect of the topology of the central circuitry,the structure of bipolar power converter is determined to be used in this system via the analysis and compare for the hackneyed topology nowadays.This paper selects MOSFET as the main switching device,select IR2110 as the driving device,and selects Silicon C8051F040 as the controller chip.Designed circuits such as peripheral hardware detection,protection,control,display and so on at the base of the relevant parameters analysis and calculation.This system takes full advantage of the controller C8051F040's resources to make the system compact and high reliability. The system control software is designed in the Keil C development environment and using C language to complete every work function compiling and debugging,traditional speed and current double loop is used.The system control algorithm selects PID,and the paper has studied the Single Neuron Self-adaptive PID algorithm.This kind of algorithm is proved to be more predominant than traditional PID algorithm by the simulation results under the Matlab/Simulink environment. The result shows that this system is reliable and stable,the control strategy and control algorithm is correct, the drive system finally reaches the target requirements.
