Robust TS fuzzy controller for helicopter via parallel distributed compensation

Abstract

A robust TS Fuzzy controller is developed for a discrete-time 2-DOF helicopter model in this work. The state feedback controller is synthesized based on fuzzy model control technique called Parallel Distributed compensation (PDC). The new algorithm control is a straightforward controller to robustly stabilize the flight attitude of 2-DOF helicopter. Thus, the proposed algorithm is used to ensure the quadratic stabilization and performance of nonlinear closed loop system and ensure robustness of fuzzy model control system. Moreover, the design conditions and criteria for the controller are formulated in the form of linear matrix inequality (LMI). The simulation response will compare the efficiency and disturbance attenuation of the designed flight controller to the other scheme.
