A Novel Prescribed Performance Control Strategy for Uncertain Nonlinear Systems

In this paper, a new finite-time prescribed performance control strategy is proposed for unknown nonlinear systems. Compared with previous research results, the controller is simple in design, with fewer parameters and greatly reduced computational complexity. In addition, the tracking error can relatively quick converge to a predefined performance boundary region in the transient process and remain in this region after reaching the steady state. Finally, the stability analysis and simulation results verify the effectiveness of the proposed controller.
