The Study Of Vector Control System Of PMSM Based On DSP

Along with the unceasing development of modernized industry, the servosystem is widespread in many systems'applications day by day, at the same time, the higher performance of the servosystem is required. The PMSM-Servosystem can achieve the performances of high accuracy, high dynamic performance, wide-scope speed regulated or orientation control, so the study of Field Orientated Control(FOC) system of PMSM has become one of the key directions in the study of digital-controlled machine tool AC servo system.This paper make an in-depth study on the Digitization PMSM Servo Driver, the main contents are: based on the mathematical model of PMSM and the principle of FOC and VC, this paper uses the Matlab/Simulink to build the simulation model of the FOC-PMSM Vector control Servo system.In this foundation, the author design and fabricate the digital servosystem basing on the TMS320LF2812 DSP and CPLD, achieving the aim of locating the field orientation of the PMSM precisely. Furthermore, the author used the CAN,SCI controller embedded in the DSP to harmonize the parameters of the multi-PMSMs, and to monitor them remotely, making the AC servo system has the network function.This paper describes the principles and the realization of the hardware and software of the servosystem detaily. Including: (1)the realization of high-performance driver the project realization are the key and difficulties.Through debug this servosystem and experiment on it, proving that this system can satisfy the basic requests of the high-performance servosystem. All the work in this paper clarifies the principles, methods and performances of the PMSM FOC system, which has the reference significance for studying the PMSM FOC system and enhancing the system's performance henceforth.
