本文针对LQR 控制在单级倒立摆控制中的不足,设计了一个LQR 结合PID 的复合控制。 并在Borland c 语言环境下编写控制程序,成功实现倒立摆的控制,其控制效果比单一LQR控制的抗扰能力有明显提高。 关键词:倒立摆 ;复合控制;LQR ;PID Abstract: To design a controller with LQR compound PID for LQR’s deficiency in single Inverted Pendulum control .And write and compile the control programs in Borland C language . The single Inverted Pendulum was controlled successfully and the result of control has a great improvement than the single LQR in rejecting a sudden disturbance.
