Summary

Based on proportional-integral-derivative (PID)/PD controls, we in the article investigate the tracking problem of a class of second-order time-varying switched nonlinear systems. To start with, for tracking a given point under arbitrary switching signals, we propose a sufficient condition about PID controller parameters, which can be implicitly described as semialgebraic sets. Successively, we consider the tracking problem under average dwell time (ADT)-based switching signals and propose an alternative sufficient condition about PID controller parameters. Especially, for tracking an equilibrium point of the system without controls, we can further simply utilize the proportional-derivative control and similarly construct corresponding semialgebraic conditions about proportional-derivative controller parameters under arbitrary switching signals and ADT-based switching signals. Finally, two examples are given to show the applicability of our theoretical results.
