Adaptive fixed-time tracking control for nonlinear systems subject to asymmetric input saturation: 点击次数：; 关键字：MODEL PREDICTIVE CONTROL; MULTIAGENT SYSTEMS; FINITE-TIME; CONSENSUS; DESIGN; 摘要：For nonlinear systems with asymmetric input saturation, an adaptive fixed-time control strategy via multidimensional Taylor network (MTN) is proposed to effectively solve the tracking control problem. Firstly, the Gaussian error function and the differential mean value theorem are used to simulate the asymmetric input saturation model, that is, the nonlinear model is transformed into a linear model with a bounded perturbation. Secondly, MTNs are applied to control the design process, which approximate the nonlinear structures with linear combination of polynomials. Thirdly, in addition to the tracking error converging to an arbitrarily small neighborhood around the origin within a fixed time, the proposed control scheme not only guarantees that any signal in the controlled system remains bounded, but also avoids the problem of finite-time control relying on the initial state. Finally, three examples are used to validate the feasibility and superiority of the scheme.; 卷号：79; 期号：; 是否译文：否
