The paper deals with the problem of constrained H∞ fuzzy control for a class of continuous-time nonlinear systems, represented by Takagi-Sugeno models. On the basis of the Lyapunov stability criterion and H∞ norm performances, the sufficient conditions of stabilization are outlined and adjusted for systems operating in a forced mode. Numerical simulation is given to illustrate the design procedure...
The paper focuses on the problem of state control for continuous-time nonlinear systems, represented by Takagi-Sugeno descriptor system. There are outlined two stability conditions, based on different forms of fuzzy Lyapunov function, one of which is appropriate to formulate sufficient conditions for the existence of the parallel distributed state compensators in terms of linear matrix inequalities...
The paper presents conditions suitable in design of state observers for a class of continuous-time nonlinear systems with unknown input, represented by Takagi-Sugeno models with unmeasurable premise variables. Based on Lyapunov inequality, the conditions are outlined in the terms of linear matrix inequalities to possess a stable structure closest to optimal asymptotic properties. Simulation results...
The paper presents the principle of fuzzy-observer-based residual generator design for a class of continuous-time nonlinear systems represented by Takagi-Sugeno models, and measurable, as well as unmeasurable premise variables. The conditions are outlined in the terms of linear matrix inequalities to possess a stable structure closest to optimal asymptotic properties. Simulation results illustrate...
One principle for designing fuzzy-observer-based fault residual generators for one class of continuous-time nonlinear MIMO system is treated in this paper. The problem addressed can be indicated as an approach given sufficient conditions for residual generator design based on fuzzy system state observers. The conditions are outlined in the terms of linear matrix inequalities to possess a stable structure...
В работе исследовалось влияние численности групп на поведение и темп роста подсвинков. С этой целью 45 поросёнков разделили на 3 группы с разной численностью: 10, 15 или 20 штук. Животных поместили в 3 соседних клетках с одинаковой площадью (4,4 м²). Анализировались: активность животных, суточные приросты и потребление корма на единицу прироста. Самые высокие суточные приросты - 320 г - а самое низкое...
