Abstract

This work presents an indicator-based switching control for a class of strict-feedback systems to exploit the potential performance improvement. The proposed approach is designed by injecting a switch mechanism into the backstepping control. An indicator is introduced to reflect the impact of the integral part on the system. The indicator-triggered control method is capable of wisely switching the control structure. Thus, the transient performance can be improved. In addition, the parameters of the proposed control scheme are optimized by Cuckoo Search algorithm to achieve the better performance. The stability is analyzed in the Lyapunov sense and the effectiveness is also verified by numerical simulations.
