步进电机的MATLAB仿真程序，采用了卡尔曼滤波，对定子电流进行估计，并估算出转子的位置和速度-Continuous time extended Kalman filter simulation for two-phase step motor，Estimate the stator currents, and the rotor position and velocity, on the basis of noisy measurements of the stator currents.

内附几十种小程序，有状态机、比较器、波形发生器、乘法器、加法器、步进电机控制器等，希望大家能用的上。-Containing dozens of small programs, for reference，This is about FPGA,a tool ,we can study,but in ourselves.
