چکیده انگلیسی
In this paper, an adaptive neural network controller is designed for a three-degrees of freedom (3-DOF) helicopter using backstepping technique. As there is uncertain time delays in the system, appropriate Lyapunov-Krasovskii functions are used to compensate the delay and neural networks are introduced to deal with the uncertainty. The feasibility of neural network approximation of unknown system functions is guaranteed over practical compact sets. It is proved that all the signals are semiglobal uniformly ultimate bounded and the connections between the tracking error and the controller parameters are analyzed in detail. Simulation and practical experiment results are given to show that the proposed controller is practically effective when tracking the time-varying signals.
