On-line control of the inverted pendulum with type-2 fuzzy logic controller

This paper presents a new type-2 fuzzy logic controller able to control a non-linear system (inverted pendulum) on-line. Type-2 fuzzy logic controllers provide us the opportunity of applying a wide variety of people opinion to control system design. This will result in minimizing the effect of uncertainties in Rule-Base fuzzy logic systems. These controllers provide more flexibility in applying human thinking in control system design in comparison to the traditional type-1 fuzzy logic controllers. However, we encounter some problems using the type-2 fuzzy logic controllers on-line because of the large volume of computations required. This paper proposes a new type-2 fuzzy controller for on-line control.
