摘要
此处论述了基于120°坐标系下的空间矢量脉宽调制(SVPWM)算法,同时在Matlab环境下实现了数字信号处理器(DSP)硬件控制算法的模拟仿真,突出了采样周期及寄存器更新周期的特点。在此基础上,提出一种包含最小脉宽控制,直流电容中点电压平衡控制及死区补偿的综合算法。利用Matlab平台将算法应用于电机控制系统,验证了其有效性。此外,完成了代码转换,并在DSP28335上实现验证。
The basic three-level space vector pulse width modulation（SVPWM） algorithm based on 120° frame is dis- cussed.Meanwhile,digital signal processor（DSP） hardware control algorithm is realized with Matlab/Simulink based on which an optimization algorithm is proposed.The synthesize algorithm including the control of minimum pulse width li- mitation, neutral point potential and dead-time compensation is presented.The effectiveness of the algorithm is verified through simulation.Code conversion is completed and the optimization algorithm is realized with DSP28335.
