[Abstract]:This paper first introduces the development of linear motor, describes the origin and structure of the cylinder switched reluctance linear motor, describes the electromechanical energy conversion model and control mode of the cylinder switched reluctance motor, and expounds the future research trend of the cylinder switched reluctance linear motor. By building a reasonable hardware circuit and designing a complete software program, the control system is debugged and the desired function of the control system is realized. Then the control strategy of the cylinder switched reluctance linear motor is introduced. The control process of the motor is described from two aspects of electric and electric power. Then, the linear electric resistance of the cylinder switch is clarified. The hardware circuit design of the machine control system, from the selection of the control chip, the signal sampling circuit, the design of the control signal output circuit and the building of the power converter, the hardware part of the control system is introduced to achieve the input signal acquisition and monitoring, the control of the output of the signal, to ensure the safe and stable operation of the motor. Under the electric mode, Using the double closed loop control strategy of frequency and current, the current hysteresis chopper control can limit the maximum current of the winding, ensure the frequency tracking and stability of the vibrator. Under the power generation mode, the voltage and current double closed loop control mode is used to adjust the load voltage in real time, and the load voltage is realtime controlled. DS PIC30F6010A and EPM570T100C are designed. 5N is the core controller, and other peripheral auxiliary circuits are designed to realize the acquisition and output of the signal. According to the different control strategies, software programming is carried out, and the system program is debugged to control the motor. On the basis of the control system hardware circuit, a linear motor testing system based on Lab VIEW is designed. First, the signal is from the signal. The design of the hardware part of the test system is introduced, such as the sensor, the conditioning circuit, the acquisition board, and so on. Then, the software programming is designed with Lab VIEW, including the user interface and the program block diagram design to realize the function of real-time display and preservation of the test system. Finally, the rationality and feasibility of the control strategy on the set up control platform are made. It has completed the electric experiment, the power generation experiment and the test system function verification, collected the related experimental waveforms, and analyzed the experiment and test results in detail. The results show that the cylinder switched reluctance linear motor has good electric and power generation performance and the control is flexible, and has good practicability.
