摘要：
In this paper, the robust adaptive tracking control problem is investigated for nonlinear time-delay systems with changing system powers. Different from the existing results, the discussed system has complicated nonlinear growing conditions and various uncertainties including the control coefficients, parameters, and external disturbances. By introducing a new robust adaptive control method, a dynamic-gain based adaptive tracking controller is constructed to guarantee the boundedness of the closed-loop systems. Besides, the tracking error can be adjusted with a satisfied precision. Finally, simulation examples are given to verify the proposed theory. (c) 2022 Elsevier Ltd. All rights reserved.
