改进型预测电压控制策略的研究

Study of improved predictive voltage control strategy

介绍了预测电压控制基本原理,针对传统的预测电压控制方法中的不足,设计了一种改进型的预测电压控制算法,采用单相空间矢量脉宽调制(SVPWM)来实现.借助MATLAB/Simulink仿真软件,对单相全桥逆变器系统进行仿真,结果表明该控制方法具有良好的控制性能.

The basic principle of predictive voltage control was introduced in the paper. In view of the weakness of the traditional predictive control method, an improved predictive voltage control algorithm was proposed which was realized by single-phase SVPWM. The result of simulation with MATLAB/Simulink software on single- phase full bridge VSI indicates that the proposed control strategy has excellent performance.
