Interval Fuzzy Type-II Controller for the Level Control of a Three Tank System

In this paper, real-time experimental as well as simulation results with an interval type-II fuzzy logic systems (IT2FLS) are compared with those of a linear quadratic regulator (LQR) for level control of three-tank hybrid system. First, a linear quadratic regulator controller has been implemented on a realtime system. Then, an intelligent controller using an interval type-II fuzzy logic has been developed and implemented on the interacting system. The IT2FLS controller has been constructed in simulations based on the model of the hybrid system and then tested on the real-time system. Lastly, a comparison between the experimental results of both controllers for the level control are made and comprehensively presented.
