摘要：

We propose a predictor tuning method for a class of uniformly observable nonlinear time-delay systems. This method is based on the multiplicity-induced-dominancy property of quasipolynomials. The predictor gains are chosen in such a way that a dominant root is located in the left half-plane, thus the prediction error converges exponentially to zero. For illustration purposes, a state prediction for the feedback control of a simple pendulum is designed and simulation results are presented.Copyright (c) 2022 The Authors.
