Real-time tracking control of underactuated pendubot using Takagi-Sugeno fuzzy systems

Abstract

By combining optimal control theory and linear regulator theory with the Takagi-Sugeno fuzzy methodology, a global optimal and stable fuzzy controller is presented to achieve trajectory tracking for a specific underactuated robot: the pendubot. The stability of the entire close-loop system is ensured by the designed optimal fuzzy controller. The paper includes a description of the pendubot system and the real-time control results.
