l∞ Performance Analysis of Feedback Systems with Saturation Nonlinearities: An Approach Based on Polytopic Representation§
نویسندگان
چکیده
In this paper, we show a method of estimating l∞-norm of an output signal of discrete-time feedback systems with saturation nonlinearities. The analysis condition for estimating l∞-norm is derived based on the parameter dependent Lyapunov function (PDLF) and is reduced to a condition based on the linear matrix inequality (LMI) representation. Further, we show that the condition is guaranteed to be less conservative than the condition based on the standard sector condition. A numerical example is provided to illustrate effectiveness of the proposed method.

Passivity-based Analysis and Control of Nonlinear Systems
A new set of tools for the stability analysis and robust control design for nonlinear systems is introduced in this dissertation. The tools have a wide range of applicability, covering systems with common types of hysteresis, as well as systems with memoryless forms such as saturation, or slope-restricted nonlinearities (e.g., parameter uncertainty or gain variation), and can be used to guarant...
متن کاملDynamic Output Feedback Control of Discrete-Time Systems with Actuator Nonlinearities
This paper considers the problem of stabilization of discrete-time systems with actuator nonlinearities. Specifically, dynamic, output feedback control design for discrete-time systems with time-varying, sectorbounded, input nonlinearities is addressed. The proposed framework is based on a linear matrix inequality approach and directly accounts for robust stability and robust performance over t...
متن کاملRegional stabilization and H1 control of time-delay systems with saturating actuators
A linear parameter varying approach is introduced for the design of a constant state-feedback controller that locally stabilizes linear systems with state time-varying delays and saturating actuators and achieves a prescribed performance level for all disturbances with uniformly bounded magnitudes. A polytopic representation is used to describe the saturation behaviour. Delay-dependent sufficie...
