自整定 PID 型模糊控制

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.

dtc for 3phases induction motor

【实例简介】 设计一个密码锁的控制电路，当输入正确代码时，输出开锁信号以推动执行机构工作，用红灯亮﹑绿灯熄灭表示关锁，用绿灯亮﹑红灯熄灭表示开锁; 在锁的控制电路中储存一个可以修改的4位代码，当开锁按钮开关(可设置成6 位至8位，其中实际有效为4位，其余为虚设）的输入代码等于储存代码时，开锁; 从第一个按钮触动后的5 秒内若未将锁打开，则电路自动复位并进入自锁状态，使之无法再打开，并发出报警信号。
