二次函数的共轭梯度法的matlab实现函数，输入相关参数即可进行迭代运算。(The function MATLAB realization of conjugate gradient method of quadratic function. )

直接转矩控制无刷直流电机的matlab仿真程序，PI闭环调节(Direct torque control brushless DC motor matlab simulation program, PI closed loop control )

用MATLAB程序软件完成Z-N法对控制器的参数整定，实现P,PI,PID控制器的分别参数整定，并求出控制器的控制参数Kp，Ti，Td。最后绘制出不同控制器控制下的及参数整定前后的单位阶跃响应图进行比较。(MATLAB program software is used to complete the parameter tuning of the controller by Z-N method. The parameters of P, PI, PID controller are adjusted, and the control parameters of the controller Kp, Ti, Td are obtained. Finally, the unit step response diagram before and after parameter tuning is plotted under different controller control.)

通过选择合适的参数，选取采样相应的采样点，进行参数计算。(By choosing appropriate parameters, select the corresponding sampling point sampling for parameter calculation.)
