永磁同步电机(PMSM)电流转速双闭环PI控制，采用矢量控制（FOC）中的id 0方式，以空间矢量脉宽调制来实现磁链圆跟踪。对负载转矩进行交轴电流前馈以抑制外负载扰动。(Permanent Magnet Synchronous Motor (PMSM) current double closed loop speed PI control, vector control (FOC) of id 0 mode, space vector pulse width modulation to achieve flux circle track. Front axle load torque AC current fed to suppress external load disturbance.)

matlab 程序汇编学习课程 上 自学matlab的最好资料(matlab study)

PPM调制的超宽带系统RAKE接收机的误码率仿真程序(BER simulation of PPM_UWB system)

说明：  自适应学习率调整法训练BP网络，讲解详细(Adaptive learning rate adjustment method training BP network, explain in detail)

This is intro to characters and it is for educational use only. Only for personal study.

说明：  两种对二阶系统进行参数辨识的最小二乘算法，一种可以直接得到输入输出之间的传递函数，一种可以解出线性的差分方程各系数，再反解得到传递函数。附带的一个二阶系统的模型，可以自行下载导入输入输出数据进行试验。(Two kinds of least square algorithm for parameter identification of second-order system, one can directly get the transfer function between input and output, the other can solve the coefficients of linear difference equation, and then get the transfer function by inverse solution. The attached model of a second-order system can download the input and output data for test.)

说明：  使用的是2019a 的matlab，对海温数据进行的eof程序分析(the eof of the matlab)
