The research in this paper focuses on a state estimation problem for paper path and heat flow control of industrial printers. The nonlinear dynamics can be approximated, up to an arbitrary accuracy, with a piecewise linear system, and an arbitrary time driven switching law. The stability and performance of the estimators are analyzed and proven based on Lyapunov theory. Simulation examples show the...
In this paper we consider the design of a nonlinear predictive controller based on a nonlinear dynamic model of the system so as to achieve tracking control for systems with input-induced nonlinearities. The economic performance under nonlinear dynamic behavior and changing operating conditions is discussed. The closed-loop properties are analyzed under suitable assumptions on the model of the plant...
This paper focuses on observer design for a flexible motion system with a state dependent output map. After rewriting the modal system to parameter varying form sufficient conditions are derived to obtain a parameter varying modal observer with bounded ℒ2 gain. These conditions translate to linear matrix inequalities (LMIs) when the time derivative of the Lyapunov function is multiconvex. The derived...
