- Abstract
- Permanent Magnet Synchronous Motor(PMSM) appeared at the 1950s century. Accompany with the development of power electronic technology and micro-computer at the 1970s century, PMSM starts to be applied in high performance speed control systems. At the 1980s century, the development of PMSM had been greatly facilitated by the development of rare earth permanent magnet materials has break through, especially the turn up of 3rd generation new rare earth permanent magnet material neodymium iron boron(NdFeB) which with high residual magnetism, strong coercivity and low price. Thus the control performance of PMSM also had qualitative leap. From then on, AC permanent magnet speed control system gradually replaced the traditional DC speed control system, to be used widely in various high performance motion control systems, and become an important branch in AC speed control field.
This thesis emphatically introduced the vector control system of BLACM and torque ripple rejection strategy of BLDCM, and explained two types of pulse-width modulation (PWM) technology. At last, established BLACM vector control system and BLDCM control system by using MATLAB/SIMULINK, and implemented simulation.
In this study, BLACM vector control experiments of two PWM algorithms were completed by programming with CCStudio software, based on TI DSP(TMS320F28035) control board. The experimental results show that there is good control effect for BLACM with vector control algorithm. By comparing the waveforms of line voltage and phase current, SVPWM algorithm is better than SPWM algorithm in switch loss and harmonic content.
From the BLDCM torque ripple suppression simulation result, it is effective to reduce the ripple of BLDCM torque with dual closed-loop BLDCM control algorithm based on CHBPWM technology.
