最速梯度法工具箱，添加方法在命令窗口中敲入pathtool，会出现一个setpath的窗口，点add folder或者add with subfolders按钮，选中你的工具箱。保存既可。任选工具箱中的一个命令，然后help一下看看是否好使。(Toolbox steepest gradient method, add the method in the command window and typing pathtool, a setpath window appears, point add folder or add with subfolders button, select your toolbox. Save both. Choose a command in the toolbox, and then help look to see if so.)

说明：  模型以永磁直驱同步发电机组为研究对象，对包括风力机、发电机及其控制系统等各部分进行控制建模与仿真，接着通过坐标变换，分析并网逆变器在d／q坐标系下的模型，采用基于d轴电网电压定向矢量控制，并通过前馈补偿，实现有功、无功的解藕独立控制.(The model takes the permanent magnet direct drive synchronous generator set as the research object, and carries on the control modeling and simulation to each part, including wind turbine, generator and its control system, and then analyzes the model of grid-connected inverter in d coordinate system through coordinate transformation. The voltage oriented vector control based on d-axis power network and feedforward compensation are adopted to realize the decoupling independent control of active and reactive power.)
