静态系统的matlab仿真，仿真得出一个幅度调制的输入输出波形。(Static system s matlab simulation, the simulation obtains an amplitude modulation the input output wave shape. )

CAD APPS is a set of Computer Aided Design (CAD) and Exploration Applications (APPS) that were developed for undergraduate Mechanical and Aerospace Engineering (MAE) students. The CAP APPS solve problems that are typically found in MAE courses. The CAD APPS have also been found to be useful to high school students, graduate students, and others.

用MATLAB进行仿真永磁直驱风力发电对网侧进行控制研究(Permanent magnet direct-drive wind power simulation)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)
