与其它高级语言相比较，MATLAB具有独特的优势：(1) MATLAB是一种跨平台的数学语言。(2) MATLAB是一种超高级语言。MATLAB平台本身是用C语言写成的，所以在编程效率，程序的可读性、可靠性和可移植性上远远超过了常规的高级语言。(3) MATLAB语法简单，编程风格接近数学语言描述，是数学算法开发和验证的最佳工具。(4) MATLAB计算精度很高。与其它语言相比，MATLAB对计算机内存、硬盘空间的要求也是比较高的。(Compared with other high-level languages​ ​ , MATLAB has unique advantages: (1) MATLAB is a cross-platform language of mathematics. (2) MATLAB is a super-high-level language. MATLAB platform itself is written in C, so the programming efficiency, readability, reliability and portability far more than the regular high-level language. (3) MATLAB syntax is simple, close to the mathematical language to describe the style of programming is a mathematical algorithm development and validation of the best tools. (4) MATLAB computing high accuracy. Compared with other languages​ ​ , MATLAB computer memory, disk space requirements are relatively high.)

用matlab做的一个比较短小的动画,需要更复杂的话可以逐步扩展(A simple animation that made by matlab , If you need to be more complex ,pls write other programs to extend it.)

说明：  ：仿真．--f~简化对单相电压型PWM逆变器的分析和设计过程。为此，文章基于状态方程建立了单相 电压型PWM逆变器的数学模型和仿真模型。仿真模型分别考虑了主电路和控制器模型，较为精确地反映了 实际情况。实验表明，以此模型为基础的控制方案是可行的。(: Simulation.- F ~ simplify the single-phase voltage PWM Inverter analysis and design process. To this end, the article was based on state equation, single-phase voltage-type PWM inverter model and simulation model. Simulation model were considered the main circuit and the controller model, more accurately reflect the actual situation. Experiments show that this model-based control scheme is feasible.)
