This paper deals with problems of parity space-based fault detection for a class of discrete-time linear Markovian jump systems. A new algorithm is firstly introduced to reduce the computation of mode-dependent redundancy relation parameter matrices. Different from the case of linear time invariant systems, the parity space-based residual generator for a Markovian jump system cannot be designed...

Abstract Efficiencies of Agricultural Credit Associations the US Farm System are measured quarterly from 2005 through 2020. A slacks-based measure based on directional distance function is used with non-performing loans included as an undesirable output. This permitted efficiency scores to be by type defined input or Generally, most were highly efficient, but there was deterioration in mean ove...

In this report, we present a geometric method for representing the classical root sensitivity function of linear time-invariant systems. The method employs gain plots that expand the information presented in the root locus plot in a manner that permits determination of both the real and imaginary components of the root sensitivity function by inspection. • ' f | ' i ;^ H-1 ;• "K I. The Root Sen...

Increasing demands regarding speed, accuracy, energy-efficiency, and costs drive the complexity of technical system. This comes along with a rising number of potential faults in a system creating a need for advanced fault diagnosis methods. To this end, this thesis is focused on the design of robust model-based fault isolation filters for linear time-invariant plants. These allow to reliably lo...

This paper proposes a discrete-time adaptive model predictive control (MPC) algorithm for a class of constrained linear time-invariant systems, which updates the estimation of system parameters on-line and produces the control input subject to the given input/state constraints. This method is based on a robust MPC algorithm using comparison model which enable us to estimate the prediction error...

In this paper an algebraic test procedure is presented to ascertain the stability of multidimensional discrete systems, which are represented in the forms of their respective characteristic equations. Further an equivalent single dimensional characteristics equation is formed for the given multidimensional characteristic equation; the coefficients of this characteristic equation are suitably ar...

The regulation theory is a very robust way to achieve the asymptotic tracking of input references on Linear Time-Invariant systems generated by an exosystem. Nevertheless, the classical regulation theory cannot be applied to the asymptotic tracking of non-sinusoidal periodic references having an infinite number of harmonics (as triangular waves). In literature many methods have been proposed to...

a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
