几篇很有参考价值的关于永磁同步电机控制的matlab仿真论文，依据此可以搭建自己的仿真框图(A few worthy of permanent magnet synchronous motor control on the matlab simulation papers, according to this you can build your own simulation block diagram)

拖拉机座椅振动特性研究,构建了拖拉机, 振动测试系统, 得到振动特性数据, 从定性角度分析了拖拉机座 椅 振动系统性能, 并通过对座椅振动频响曲线的辨识建立数学模型, 得 到弹性系数、 阻尼系 数、 固有频率等系统 振 动特性参数, 为进一步进行拖拉机座椅的减振研究和设计提供了支撑(St udy on Vibrati on Characteristics of t he Tractor Seat)

说明：  这是一个自相关法求AR模型谱估计的matlab程序。(This is a self - correlation method for AR model spectrum estimation matlab program.)

This simulink model simulates the damped driven pendulum, showing it s chaotic motion. theta = angle of pendulum omega = (d/dt)theta = angular velocity Gamma(t) = gcos(phi) = Force omega_d = (d/dt) phi Gamma(t) = (d/dt)omega + omega/Q + sin(theta) Play with the initial conditions (omega_0, theta_0, phi_0 = omega(t=0), theta(t=0), phi(t=0)) and the system parameters (g, Q, omega_d) and the solver parameters/method. Chaos can be seen for Q=2, omega_d=w/3. The program outputs to Matlab time, theta(time) & omega(time). Plot the phase space via: plot(mod(theta+pi, 2*pi)-pi, omega, . ) Plot the Poincare sections using: t_P = (0:2*pi/omega_d:max(time)) plot(mod(spline(time, theta+pi, t_P), 2*pi)-pi, spline(time, omega, t_P), . ) System is described in: "Fractal basin boundaries and intermittency in the driven damped pendulum" E.
