Fuzzy control of an inverted pendulum systems in MATLAB/Simulink

This paper presents the effect of the performance tuning a fuzzy controller in terms of the integral of the absolute error value in order to control the position of classical nonlinear problem of inverted pendulum. The methodological development is based on the theory of fuzzy logic controller design considering the expertise acquired on the dynamics of the mechanical system under consideration, thus avoiding the development of rigorous models to represent the dynamics. A set of simulations to evaluate the driver capabilities were developed for the nonlinear system model to different tuning values, which uses 7 membership functions for position and 3 for speed, allowing to determine the sensitivity of the membership functions based on the operational response of this system.
