This paper deals with the delay-dependent robust H∞ filter for a class of Takagi-Sugeno (T-S) fuzzy descriptor time-delay systems with parameter uncertainties. The uncertainties in the system are timevarying and bounded. By simplifying the T-S fuzzy descriptor system to the time-delay system, and base on Lyapunov stability theory in time-delay system, a sufficient condition on the existence of ...

Linear descriptor systems form the natural way in which linear models of physical systems are delivered from an object-oriented modeling tool like Modelica. Linear descriptor systems are also known as linear differentialalgebraic equations in the continuous-time case. If some parameters in such models are unknown, one might need to estimate them from measured data from the modeled system. This ...

Magnetic Resonance Imaging (MRI) is one of the important resources for identifying abnormalities in human brain. This work proposes an effective Multi-Class Classification (MCC) system using Binary Robust Invariant Scalable Keypoints (BRISK) as texture descriptors classification. At first, potential Region Of Interests (ROIs) are detected features from accelerated segment test algorithm. Then, ...

This paper presents a new and less conservative condition for the robust stability test of discrete-time polytopic systems by using a descriptor system approach. The stability condition is formulated in terms of a set of linear matrix inequalities and can be easily adapted for robust controller synthesis. The developed results can be viewed as a discretetime counterpart of the continuous-time o...

This paper discusses the reliable and robust H∞ control problem for a class of descriptor systems with parametric uncertainties and external disturbances in the case of actuator failures. By solving a set of matrix inequalities, a sufficient condition and a controller are obtained for the reliable and robust H∞ control problem of the descriptor systems. Introduction Descriptor systems are gener...

The structure uncertain non-linear descriptor systems have been considered. A controller feedback and open loop stabilization of non-linear perturbed descriptor system have been developed using Lyapunov function approach and finite time stability principle. The theoretical justifications with the necessary requirements and illustration have also been presented.

This report treats some basics on parameter identification in linear time invariant descriptor systems, both time continuous and time discrete. It is shown how identification methods for normal state space systems can be used by transforming the descriptor system to state space form. It is also examined how identification can be performed in the frequency domain.
