[Abstract]:Switched Reluctance Motor (SRM) has many excellent performances, such as high reliability, high efficiency, low cost, wide speed range and so on. The starting current is small, the starting torque is large, and the mechanical centrifugal force is very large. It is a potential mechatronics system. This paper has carried out the following research: this paper designs a three-phase 6/4 pole switched reluctance motor drive control system with C8051F120 and CPLD as the control core. This paper summarizes the research status of SRM in structure design and control theory at home and abroad. In chapter 2, the basic theory of SRM is discussed in detail. Chapter three focuses on the design of motor ontology. A set of 6/4 300W motor entity is developed. The finite element model of the motor is established by using Ansoft software, and the 2D and 3D electromagnetic performance simulation based on Maxwell 2D / 3D is carried out. The structural parameters are optimized and the feasibility of the prototype structure is verified. Chapter 4th is the hardware design of the system. With C8051F020 and CPLD dual control chip as the core, the power conversion circuit, drive circuit, position signal detection circuit, bus overvoltage and overcurrent detection circuit of switched reluctance motor drive control system are designed. The hardware circuit such as chopper circuit and power supply circuit make full use of the advantages of combined control of double controllers and have strong processing ability. Chapter 5th studies the SRM control software, which combines the functions of motor starting and stopping, forward and backward rotation, speed regulation and so on. The main program and interrupt subroutine of the system are designed based on C8051F120 microcontroller, the flow chart of the program is given, and the CPLD logic processing program is written by using Quartus software. In this paper, the drive control system of switched reluctance motor is designed, and the SRM structure design, hardware circuit design and control software research are introduced. The system has compact structure and low control cost. The function is comprehensive, has the higher application value.
