Abstract
This article addresses the problem of tracking control for an unknown nonlinear system with time-varying bounded disturbance subjected to prescribed performance and input constraints (PIC). Since the simultaneous prescription of PIC involves a tradeoff, we propose an analytical feasibility condition to prescribe a feasible PIC, which also results in a feasible initial state set as a corollary. In addition, we propose an approximation-free controller to ensure the tracking performance meets the prescribed PIC. The effectiveness of the proposed approach is demonstrated through numerical examples.
期刊介绍：
In the IEEE Transactions on Automatic Control, the IEEE Control Systems Society publishes high-quality papers on the theory, design, and applications of control engineering. Two types of contributions are regularly considered:
1) Papers: Presentation of significant research, development, or application of control concepts.
2) Technical Notes and Correspondence: Brief technical notes, comments on published areas or established control topics, corrections to papers and notes published in the Transactions.
In addition, special papers (tutorials, surveys, and perspectives on the theory and applications of control systems topics) are solicited.
