In this paper, we propose novel LMI conditions for the stability and l2 gain performance analysis of discrete-time linear periodically time-varying (LPTV) systems. These LMIs are convex with respect to all of the coefficient matrices of the LPTV systems and this property is promising when we deal with several control system analysis and synthesis problems. For example, we can apply those LMIs s...

Systems with delays are a specific group of dynamic systems. The fact that some delays can be short and some can be long makes system analysis and control design much more complex. In this paper we present a proposal to solve the problem of stability and control design of continuous time systems with time-varying delays. Based on the Lyapunov-Krasovskii functional the stability condition is der...

In this paper, the global exponential stability analysis problem is considered for a class of recurrent neural networks (RNNs) with time delays and Markovian jumping parameters. The jumping parameters considered here are generated from a continuous-time discrete-state homogeneous Markov process, which are governed by a Markov process with discrete and finite state space. The purpose of the prob...

In this work we study a new approach of fault tolerant control schema.The suggested strategy is an active Fault Tolerant Control (FTC) strategy that reconfigures the controller on-line taking into account changes due to the faults where both the block of fault detection and the block of the controller are formulated as a Linear Matrix Inequality (LMI) problem. The problem of fault estimation is...

The focus of the research is on the design of a decentralized output feedback controller for a class of large-scale systems using linear matrix inequalities (LMI). The class of large-scale systems is characterized by unmatched nonlinear interconnection functions that are uncertain but quadratically bounded in the overall system state. An elegant LMI solution to the problem is provided in (Silja...

In this paper an approach for robust anti-windup compensation design for PID controllers based on the characterization of H2 and H∞ norms as Linear Matrix Inequalities (LMI) is presented. The robustness is considered by assuring the closed loop performance, spite of unknown changes on the actuator saturation limits. The stability and performance margins are evaluated from H2 and H∞ norms of the...

In this paper, a high-gain interval observer (HGIO) for class of partially linear continuous-time systems with sampled measured outputs in the presence bounded noise and additive disturbances is proposed. The design HGIO formulated Linear Matrix Inequality (LMI) framework. gain designed to satisfy cooperative property using time-varying change coordinates based on pole placement separate LMI re...

Blood metabolites can be detected as low-mass ions (LMIs) by mass spectrometry (MS). These LMIs may reflect the pathological changes in metabolism that occur as part of a disease state, such as cancer. We constructed a LMI discriminant equation (LOME) to investigate whether systematic LMI profiling might be applied to cancer screening. LMI information including m/z and mass peak intensity was o...

BACKGROUND The relative benefit of higher statin dosing in patients with peripheral artery disease has not been reported previously. We compared the effectiveness of low- or moderate-intensity (LMI) versus high-intensity (HI) statin dose on clinical outcomes in patients with peripheral artery disease. METHODS AND RESULTS We reviewed patients with symptomatic peripheral artery disease who unde...
