Abstract :
اين مقاله با تحليل پايداري نمايي وابسته تاخيري و پايدارسازي سيستمهاي پرشي ماركوي T-S فازي زمان – پيوسته با تاخير متغير زماني وابسته نما مرتبط است. با ساخت يك تابعيLyapunov-Krasovskii جديد و استفاده از برخي از تكنيكهاي پيشرفته ، شرايط بازدارنده كمتري ارايه گرديده تضمين كند كه سيستم حلقه – بسته ميانگين – مجذور بطور نمايي پايدار باشد. سپس شرايط پايدارسازي بدست آمده وكنترل كننده هاي فازي توسط مجموعه اي از جوابهاي LMI ها قابل حصول ميباشند. با بكار بردن الگوريتم بهينه كران بالاي تاخير – زماني را كه سيستم مي تواند پايدار شود داده شده است. دو مثال ارايه گرديده تا تاثير وپتانسيل روشهاي ما را نشان دهد.
Abstract :
This paper is concerned with delay-dependent exponential stability analysis and stabilization for continuous-time T-S fuzzy Markovian jump systems with mode-dependent time-varying delay. By constructing a novel Lyapunov-Krasovskii functional and utilizing some advanced techniques, less conservative conditions are presented to guarantee the closed-loop system is mean-square exponentially stable. Then, the stabilization conditions are derived and the fuzzy controller can be obtained by solving a set solutions of LMIs. The upper bound of time-delay that the system can be stabilized is given by using an optimal algorithm. Two examples are presented to illustrate the effectiveness and potential of our methods.
