Adaptive tracking control of high-order MIMO nonlinear systems with prescribed performance Research Articles

Xuerao Wang, Qingling Wang, Changyin Sun,wangxuerao@seu.edu.cn,qlwang@seu.edu.cn,cysun@seu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 7,   Pages 986-1001 doi: 10.1631/FITEE.2000145

Abstract: In this paper, an observer-based adaptive tracking control scheme is developed for a class of uncertain multi-input multi-output nonlinear systems with or without . A novel finite-time is constructed to estimate the system uncertainties and external disturbances. To guarantee the , an error transformation is applied to transfer the time-varying constraints into a constant constraint. Then, by employing a barrier Lyapunov function and the backstepping technique, an observer-based tracking control strategy is presented. It is proven that using the proposed algorithm, all the closed-loop signals are bounded, and the tracking errors satisfy the predefined time-varying performance requirements. Finally, simulation results on a quadrotor system are given to illustrate the effectiveness of the proposed control scheme.
