Abstract

A new fuzzy controller for stabilization control of inverted pendulum systems is presented based on the Single Input Rule Modules (SIRMs) dynamically connected fuzzy inference model. The fuzzy controller has four input items, each with a SIRM and a dynamic importance degree. The SIRMs and the dynamic importance degrees are designed such that pendulum angular control has priority over cart position control. It is made clear that the fuzzy controller performs the pendulum angular control and the cart position control in parallel, and switching between the two controls is realized by automatically tuning the dynamic importance degrees according to control situations. The simulation results show that the proposed fuzzy controller has a high generalization ability to stabilize completely a wide range of the inverted pendulum systems within 9.0 s for an initial angle up to 30.0°.

倒立摆系统的模糊镇定控制
基于单输入规则模块(sims)动态连接模糊推理模型,提出了一种用于倒立摆系统镇定控制的模糊控制器。模糊控制器有四个输入项,每个输入项都有一个SIRM和一个动态重要度。设计了单摆角控制优先于小车位置控制的sims和动态重要度。明确了模糊控制器并联进行摆角控制和小车位置控制,并根据控制情况自动调整动态重要度,实现两种控制的切换。仿真结果表明,所提出的模糊控制器具有较强的泛化能力,可在9.0 s内实现大范围倒立摆系统的完全稳定,初始角度可达30.0°。
