TL;DR: A new representation of discrete bilinear model by developing its coefficients associated to the input, to the output and to the crossed product on three independent Laguerre orthonormal bases to ensure a significant parameter number reduction as well as simple recursive representation.

TL;DR: In this article, a method for monitoring an industrial process including a succession of steps P1 to Pn for transforming a product from an initial state Yo to a final state Yn, in which each step Pi and each state Yi are characterised by representative parameters, is characterised in that, for each step Pn, the parameters representative of the state Yi of the product are calculated with the aid of a mathematical model Fi representative of each step, on the basis of parameters representative Yi-1 before the step and of the parameters representing of the step Pi.

TL;DR: In this article, a fault tolerant control (FTC) design for nonlinear Takagi-Sugeno (T-S) models with measurable premise variables is investigated, where a PI observer is needed to estimate simultaneously the faults and the faulty system states.

TL;DR: In this article, a nonlinear extension of principal component analysis (PCA) is developed for sensor failure detection and isolation (FDI) to an air quality monitoring network via nonlinear PCA, which is obtained by using two cascade three layer RBF-Networks.

TL;DR: This paper addresses the design of adaptive observer for uncertain descriptor multi-models (MM), affected by unknown inputs (actuator faults) and subject to unknown model parameter variations, in the context of fault tolerant control (FTC) strategy.
