Two-Degree-Of-Freedom Fuzzy Control in Decentralized Trajectory Tracking

Abstract

The paper presents structures and a systematic development method for two-degree-of-freedom (2-DOF) fuzzy controllers with non-homogenous dynamics with respect to the two input channels. The proposed controller structures are dedicated to a low order plant, which is specific to the field of servo-systems. The design relations are based on the fact that, in some certain conditions, fuzzy controllers and linear development methods are applicable for this situation. The presentation points out that the proposed 2-DOF fuzzy controllers can be applied in robot control and ensure good control system performance with respect to reference input and disturbance actions.
