说明：  混合Newton发求最小值.原理是基于Newton法，求解非线性方程。利用和最速下降法混合，避免了Newton的不足(ues mix Newton method to solve the problem: min f(x))

An extended Kalman filter (EKF) is employed to estimate the motor state variables by only using measurements of the stator fine voltages and currents. When applying the EKF, it was necessary to solve some specific problems related to the voltage and current waveforms of the BLDCM

小球碰撞，很有意思的一段MATLAB程序，在网上找到的，希望作者不要介意(sphere collision. it is an interesting code by matlab.)

带有MPPT功能的光伏阵列Matlab通用仿真模型(PV array with MPPT function Matlab generic simulation model)

The PID controller is the most widely used controller in industrial systems. However, appropriately tuning a PID controller is not an easy task although it has only three parameters at most. This submission provides a tool for beginners to learn PID tuning.
