Abstract:

The issue of event-based asymmetric predetermined performance control (PPC) has been addressed for p-normal nonlinear systems with time-varying unknown control coefficients. A set of Nussbaum functions is introduced, capable of addressing both single and multiple unknown control coefficients. To achieve asymmetric PPC, a switching constraint scheme is proposed. Subsequently, an adaptive fuzzy controller based on dynamic events is developed. Improved techniques for approximating the unknowns of a system using fuzzy logic systems, while dynamic events are employed to reduce the frequency of controller updates. Using Lyapunov stability theory, it is proven that all signals in the closed-loop system remain bounded, and the tracking error is confined within the specified asymmetric boundaries. Eventually, the effectiveness of the present scheme is demonstrated by the simulation of three examples.

I. Introduction

In Recent years, -normal systems have garnered significant attention from scholars due to their ability to elucidate various physical systems, such as the cone valve model [1], the wing section model [2], and the spring physical system [3], to name a few. To address challenges arising from system power, the introduction of a power integral technique has been proposed [4], yielding numerous compelling outcomes in the realms of stabilization [5], [6], [7] and tracking problems [8], [9], [10]. However, it is noteworthy that these achievements are contingent upon the availability of known control coefficients.
