Abstract:
This research considers the problem of predefined-time adaptive neural control for high-order nonlinear systems with dynamics uncertainties. Through the application of neural networks, the unknown nonlinear functions of the systems are approximated. In order to avoid the "complexity explosion problem", a novel predefined-time dynamics surface is designed for high-order nonlinear systems. Regarding the dynamics uncertainties existing within the systems, this paper designs and introduces a modified predefined-time dynamics signal to address the aforementioned issue. By using a backstepping design scheme, the neural predefined-time control approach is proposed so that all signals in considered systems are bounded within a predefined time. To verify the validity of the proposed method, an illustrative example is presented.

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
