针对具有多变量、非线性特性的倒立摆系统,提出了一种基于T-S模型的双闭环串级模糊控制方法。在该方法中,内环控制倒立摆的角度,外环控制倒立摆小车的位移,并对双闭环参数耦合实现了解耦,降低了系统设计的难度和复杂度。数字仿真结果表明了该方法的可行性。
For the inverted pendulum system with multi-variable and nonlinear characteristic, a double closed-loop cascade fuzzy control approach was put forward based on Takagi-Sugeno fuzzy model. In this approach, the angle of inverted pendulum is controlled by the inner-loop and the displacement of the small cart is controlled by the outer-loop, and the coupling between angle parameters and displacement parameters can be decoupled successfully. The difficulty and complexity of control system are reduced. Digital simulation shows that this method is effective.
