In this work, we develop a discrete control scheme based on an approximate feedback linearization method and the reversing trajectory method. This allows estimating and enlarging the asymptotic region of stability around the operating points. The main objective of the very work is to implement the methodology of feedback linearization techniques for controlling nonlinear discrete time systems. The presented approach is applied to a control problem in a CSTR. The simulation results, demonstrate the increasing effectiveness and the interesting local performance of the proposed approach.

To begin with, two advanced nonlinear model-based control design methods are compared in view of industrial applications. The nonlinear repetitive control model and gain-scheduling control approach are actually based on the polynomial feedback linearization formalism and on a non-Lyapunov method for the estimation of the attraction domains. Again, an input control which guarantees closeness and swiftness along a desired trajectory is consequently constructed. Accordingly, the comparative evaluation is carried out on a CSTR reactor model. Based on an analysis of simulation scenarios, the synthesized controller is validated with respect to trajectory tracking performance and implementation issues. Last of all, our results are illustrated via a numerical simulation.

This paper deals with the design and analysis of residual generators for polynomial systems. The computation of a bank of residual generators is exploited for fault detection and isolation of a ship electric propulsion system, characterized by a nonlinear model, in the presence of disturbance. The simulation results shows how a fault detectability/isolability procedure can be made on a practical system.
