Abstract EN
An adaptive neural control method is proposed in this paper for the flexible air-breathing hypersonic vehicle (AHV) with constraints on actuators.
This scheme firstly converts the original control problem with input constraints into a new control problem without input constraints based on the control input saturation function.
Secondly, on the basis of the implicit function theorem, the radial basis function neural network (RBFNN) is introduced to approximate the uncertain items of the model.
And the minimal-learning-parameter (MLP) technique is adopted to design the adaptive law for the norm of network weight vector, which significantly reduces calculations.
Meanwhile, the finite-time convergence differentiator (FD) is introduced, through which the model state variables and their derivatives are accurately estimated to ensure the control effect.
Finally, it is theoretically proved that the closed-loop control system is stable.
And the effectiveness of the designed controller is verified by simulation.
