Abstract:
|
A new adaptive nonlinear state predictor (ANSP) is presented for a class of
unknown nonlinear systems with input time-delay. A dynamical identification with neu-
ral network (NN) is constructed to obtain NN weights and their derivatives. The future
NN weights are deduced for the nonlinear state predictor design without iterative calcu-
lations. The time-delay and unknown nonlinearity are compensated by a feedback control
using the predicted states. Rigorous stability analysis for the identification, predictor and
feedback control are provided by means of Lyapunov criterion. Simulations and practical
experiments of a temperature control system are included to verify the effectiveness of
the proposed scheme. |
