数据采集终端程序 0611(2)

为了避免复杂的三角函数和求根运算，便于数字信号处理器的实时运算，提出一种新 的SVPWM算法。采用SPWM中调制波与载波相比较的规则采样思路，通过在静止坐标系下直接 计算每个参考电压矢量所对应的三相调制波的函数值，进而得到每相电压在一个PWM周期中的 占空比．该算法的主要特点是计算简单，只需要普通的四则运算，适用于数字化系统。在扇区划 分和占空比饱和的处理上较传统SVPWM算法更简便，且过调制范围也略有拓展，具有很大的实 用性。仿真和实验结果证实了该算法的有效性。(In order to avoid complex trigonometric and root operation, ease of operation, real-time digital signal processor, propose a new SVPWM algorithm. Using SPWM modulation wave in comparison with the carrier' s regular sampling ideas, through the stationary coordinate system directly calculated for each reference voltage vector corresponding to the phase modulation wave function value, and then get each phase voltage in a PWM period accounted for air ratio. The main features of the algorithm is to calculate simple and requires only ordinary arithmetic for digital systems. Saturation in the sector division and duty cycle of the treatment more convenient than traditional SVPWM algorithm, and also a slight over-modulation range expansion, with great practicality. Simulation and experimental results confirm the effectiveness of the algorithm.)

Convert DCM to JPG. It is wriiten by C++. It is very suitable for junior.

gh0st的源码可以支持win7下使用 (gh0st source supports use under win7)

< 绿林卫士>>是作者在97年，临近大学毕业的时候开发的，当时国内盛行红警，游戏开发行业才刚刚开始。虽然本游戏在98年初参加ENIX全球大赛获优胜奖，但很多设计思想还不成熟。不过对于想入门入门开发游戏的程序爱好者来说这是个不错的参考。 本游戏利用了当时刚推出的DirectX 2D和DirectSound技术。 由于动画太大，程序略去了Avi文件，请启动程序后按ESc键进入菜单。 (<Greenwood defender>> is a writer in 97 years, when graduating from college near the development, when the prevalence of domestic红警, game development industry has just begun. Although the game early in the 98 to participate in the Global Competition by Enix prize, but many are not yet ripe for design ideas. But like the development of entry-entry procedures for the game lovers, this is a good reference. The game made use of then newly introduced technology DirectX 2D and DirectSound. As a result of too much animation, the program omits the Avi file, please start the process by the ESC key to enter the menu.)
