Abstract
In this paper, an Adaptive RBFNN global fast dynamic terminal sliding mode control (ARBFNNGFDTSMC) is
designed to situate the main and tail angles of a twin rotor MIMO system (TRMS). The control objective is to
stabilize the TRMS in a reference position or follow a predefined trajectory. An adaptive RBFNN has been used in
order to identified unknown nonlinear dynamics of the TRMS. In addition, another adaptive control expressions
has been added to diminish the wind gusts, external disturbance effects, and to compensate the estimation errors
of the adaptive RBFNN. Moreover, the stability analysis in closed-loop is assured by using Lyapunov method. The
developed controller is applied to the TRMS with cross coupling between tail and main subsystems without
decoupling procedure. Experimental results prove the good control tracking performance in presence of wind
gusts and external disturbances.
