This article presents a new approach of systematic determination of models base for the multimodel approach. The application of this approach requires, first, to classify a numeric data by exploiting the self-adapting artificial Kohonen neural-networks. The obtained data relative to the clusters are then exploited for both structural and parametric… (More)

In this paper, we consider the control of time delay system by Proportional-Integral (PI) controller. By Using the HermiteBiehler theorem, which is applicable to quasi-polynomials, we seek a stability region of the controller for first order delay systems. The essence of this work resides in the extension of this approach to second order delay system, in… (More)

This paper proposes and discusses a model predictive control approach to hybrid system, with discrete and continuous inputs. The hybrid model of two tank system is translated into mixed logical dynamical (MLD) form, which considering all constraints in the physical plant, such as maximum (flow in the pomp) and maximum level in the tank. The resultant system… (More)

The evaluation of validities is a fundamental step in the design of the multimodel approach. Indeed, it is thanks to validities that we estimate the contribution of each base-model in the reproduction of the behavior of the global process in a given operating area. These coefficients are calculated most commonly by the approach of the residues formulated by… (More)

The “delay scheduling” procedure is a recent concept for the design of control system. “Delay scheduling” strategy manipulates existing delays in the feedback as a control parameter which is increasing in order to recover stability. Indeed, the system should have many stable regions in the time delays domain. To do this, a recent… (More)

In this paper, a linear quadratic optimal control problem for linear descriptor systems is investigated. The optimal control is synthesized as derivative state feedback which guarantees that the closed loop system is stable and that minimizes quadratic criteria expressed a performance level. The steady state derivative feedback optimal gain can be computed… (More)

This paper provides a technique for admissibilization of linear descriptor systems by state derivative feedback. Sufficient conditions are derived for the closed-loop system to be admissible are given in terms of linear matrix inequalities (LMIs). So, these conditions are reliable using numerical computations. An explicit expression of the desired… (More)

A new control strategy is presented in this paper, based on previous works limited to the control of the capacitor voltages considered as the outputs of a three cell converter. An additional control input is proposed to this latter in order to obtain the desired current output. The experimentations performed on a multicellular converter are presented and… (More)

This paper treats the problem of continuous-time model identification with unknown time delays from sampled data. The proposed method estimates the plant and the time delays in a separable way. More precisely, the plant is estimated by the standard recursive Least Square algorithm while the time delays are explicitly estimated by the Gauss-Newton algorithm.… (More)

This paper, discuss the observability of the multicellular converter which is classified as a switching hybrid system. Several observers will be used for the capacitors voltage estimation despite the partial observability of the system.
