Vector Control System Of Permanent Magnet Synchronous Motor Based On Input Current Space Vector-Output Hysteresis Current Control Modulated Matrix Converter

Permanent magnet synchronous motor is small in size, light weight, low inertia, high efficiency, the rotor without heating characteristics. Once there it will in high-performance servo system has been widely applied, such as industrial robots, CNC machine tools, flexible manufacturing systems, various automation equipment, and other fields. The evolution of vector control technology has enabled PMSM to possess as good performance as that of DC motors and become the preference of modern drive systems. Also AC-AC matrix converters hold good potentialities in AC drive systems owing to its unity power factor, without bulky capacitors, and sinusoidal input currents. Therefore, the combination of the PMSM vector control and the matrix converter has recently arrested substantial attentions from scholars both at home and abroad.The present paper presents the research on the vector control system of matrix converter-permanent magnet synchronous motor (MC-PMSM) based on input current space vector-output hysteresis current modulation, and introduce theoretical analyses and simulation research about the implementation method, the input current quality and the speed regulating performance of the system. The MC-PMSM system prototype is designed and implemented, in which the digital signal processor (DSP) and the complicated programmable logic device (CPLD) act as the control units. Then experiments are also performed.Main contents concerned in the paper are as follows:The switch state combinations of MC-PMSM vector control system, which is based on the input current space vector-output hysteresis current modulation, are analyzed at full length, providing basis for the designing of the control system.The modle of MC-PMSM vcotor control system which based on the input current space vector-output hysteresis current modulation is build, and then the simulation and analysis are taken.Finally, the platform of the MC-PMSM vector control system is constructed in the present research on which the correctness and feasibility of the methods provided in the paper are verified, highlighting the significance of the present research for further researches.
