The Design Of Switched Reluctance Motor Drive

Switched Reluctance Motor Drive system(SRD for short) is a kind of new-style drivesystem,it have already become a hot research subject.This paper uses an0.75KW four-phase8/6pole SRM as the research object,completes the research and design of the drive systembased on the SRM’s ideal linear model.The paper firstly introduces the research of SRD both at home and abroad nowadays,thendescribes the basic structure and the characteristics of the system.Based on its ideal linearmodel,the paper analysed the relation of the motor’s flux,current,torque and otherparameters.The paper summed up the impact factors of each parameter,and finally,lodges amethod of control for this drive system in practice.At the aspect of the topology of the central circuitry,the structure of bipolar powerconverter is determined to be used in this system via the analysis and compare for thehackneyed topology nowadays.This paper selects MOSFET as the main switchingdevice,select IR2110as the driving device,and selects Silicon C8051F040as the controllerchip.Designed circuits such as peripheral hardware detection,protection,control,display and soon at the base of the relevant parameters analysis and calculation.This system takes fulladvantage of the controller C8051F040’s resources to make the system compact and highreliability.The system control software is designed in the Keil C development environment andusing C language to complete every work function compiling and debugging,traditional speedand current double loop is used.The system control algorithm selects PID,and the paper hasstudied the Single Neuron Self-adaptive PID algorithm.This kind of algorithm is proved to bemore predominant than traditional PID algorithm by the simulation results under theMatlab/Simulink environment.The result shows that this system is reliable and stable,the control strategy and controlalgorithm is correct, the drive system finally reaches the target requirements.
