Some new delay-dependent stability criteria are derived by takingthe relationship between the terms in the Leibniz-Newton formula into account. Free weightingmatrices are given to express the relationship between the terms in the Leibniz-Newton formula andthe new criteria are based on linear matrix inequalities such that the free weighting matrices can beeasily obtained. Moreover, the stability criteria are also used to design the state-feedback controller.Numerical examples demonstrates that the proposed criteria are e?ective and are an improvementover the previous papers.展开更多

A criterion for nominal systems is presented by taking the relationship between the terms in the Leibniz-Newton formula into account, which is described by some free-weighting matrices. In addition, this criterion is extended to robust stability of the systems with time-varying structured uncertainties. All of the criteria are based on linear matrix inequality such that it is easy to calculate the upper bound of the time-delay and the free-weighting matrices. Numerical examples illustrate the effectiveness and the improvement over the existing results.展开更多

Aquaculture can alleviate the impact of the food crisis and provide people with different sources of income. However, there are still some problems in the development of aquaculture, such as low intelligence level, high labor intensity, serious environmental pollution and low production efficiency, which lead to the slow development of aquaculture industry. The construction of intelligent aquaculture monitoring system can improve the aquaculture efficiency, relieve the aquaculture pressure of aquaculture personnel, and does not require the aquaculture personnel to invest more economic costs, which meets the needs of modern aquaculture. At the same time, it plays an important role in solving the problems existing in aquaculture and promoting the development of aquaculture industry.展开更多
