我们设计的异步电机变频调速器以TMS320F28035芯片为控制核心，通过输出三相PWM波控制智能功率模块IPM驱动三相异步电机。我们使用空间矢量SVPWM算法，并对其进行了优化。采用异步电机无传感器测速算法省去了昂贵的光电编码器，大大节省了成本。同时开创性的研发了自动根据运行环境调节的自适应变频算法，使我们的变频调速器可以在电网条件恶劣的乡村山区工作，由此该变频器已被一家民用水泵生产企业预订。(We design the asynchronous motor frequency conversion governor with TMS320F28035 chip as the control core, and output three-phase PWM wave to control the intelligent power module IPM to drive the three-phase asynchronous motor. We use space vector SVPWM algorithm and optimize it. The sensorless speed measurement algorithm of asynchronous motor eliminates the expensive photoelectric encoder and greatly saves the cost. At the same time, pioneering research automatic conversion algorithm based on adaptive adjustment of the operating environment, we can make VVVF in power grid conditions of rural area, thus the inverter has been a civil pump manufacturer reservation.)

本文综述了风力发电机组的电气控制。在介绍风力涡轮机特性的基础上介绍了双馈异步发电系统和永磁同步全馈发电系统，具体介绍了双馈异步发电系统的运行过程，最后简单介绍了风力发电系统的一些辅助控制系统。-This paper reviews the wind turbine electrical control. In introducing the characteristics of wind turbines based on the introduction of the doubly-fed induction and permanent magnet synchronous generating system-wide power-fed systems, the specific introduction of the double-fed asynchronous operation of the process of power generation systems, and finally a brief account of the wind power system ancillary control system .

说明：  一个吃豆豆的游戏，游戏功能很简单，操作应该不用累赘了，用c语言写的~呵呵，不会很落后吧~(an eating Dou game, the game is very simple functions, operators do not have to be cumbersome, with the written language c ~ Oh, it will not be very backward ~)

说明：  这是一款非常实用的计算器,我认为其实用程度远远胜过Windows系统提供的计算器.主要特色是支持多项式运算,即可以一次输入整个多项式,并能够识别运算的优先级(利用堆栈实现)(This is a very practical calculator, I think far better than using Windows systems calculator. The main feature of polynomial Operational support, which can import an entire polynomials, and to identify the priority level computing (using stack realization))

实现电位器控制舵机的作用旋转，实现了51单片机的AD转换，讲转换的制再转换成舵机的角度(The potentiometer controls the action and rotation of the steering gear, realizes the AD conversion of 51 single chip computer, and then converts the conversion system into the angle of the steering gear.)
