Adaptive Dynamic Surface Control: Stability Analysis Based on LMI
In this paper, quadratic stability of adaptive dynamic surface control for a class of nonlinear systems in strict-feedback form is analyzed in the framework of linear matrix inequality. While the existence of controller gains and filter time constants for semi-global stability was theoretically proved in the literature, it is not sufficient to describe how a set-point value and parameter update...
متن کاملAn LMI-based Analysis of Stability Margins in Adaptive Flight Control
In this paper we show that, by casting the error dynamics of an adaptive control system into a Linear Parameter Varying form, we can apply linear matrix inequality techniques and calculate stability margins for adaptive control systems. More precisely, by taking the viewpoint that nonlinear systems, in particular some classes of adaptive controllers, can be parameterized by a set of linear syst...
متن کاملAnalysis of Speed Control in DC Motor Drive Based on Model Reference Adaptive Control
This paper presents fuzzy and conventional performance of model reference adaptive control(MRAC) to control a DC drive. The aims of this work are achieving better match of motor speed with reference speed, decrease of noises under load changes and disturbances, and increase of system stability. The operation of nonadaptive control and the model reference of fuzzy and conventional adaptive contr...
متن کاملDigital Repetitive Control under Nonuniform Sampling: An LMI Stability Analysis
Digital repetitive control is a technique which allows tracking periodic references and/or rejecting periodic disturbances. Repetitive controllers are usually designed assuming a fixed fundamental frequency for the signals to be tracked/rejected and its main drawback being a dramatic performance decay when this frequency varies. A usual approach to overcome the problem consists of an adaptive c...
متن کاملMultirate Digital Control for Fuzzy Systems: LMI-Based Design and Stability Analysis
Abstract: This paper studies an intelligent digital control for nonlinear systems with multirate sampling. It is worth noting that the multirate control design is addressed for a given nonlinear system represented by Takagi-Sugeno (T-S) fuzzy models. The main features of the proposed method are that i) it is provided that the sufficient conditions for stabilization of the discrete-time T-S fuzz...
