In this paper, the problems of state estimation are investigated for switched linear systems with average dwell time (ADT) switching in both continuous-time and discrete-time contexts. First, a set mode-dependent Luenberger-type observers is designed subject to ADT that synchronous estimated systems. Then, more practical case delayed also considered, which implies multiple-mode observer be has lag case, asynchronous signals combined as preliminary attempt, upon sufficient conditions...

This study is concerned with robust finite-time stability and stabilisation of a class switched positive systems. By using the multiple linear copositive Lyapunov function approach, sufficient conditions boundedness are constructed, respectively. l 1-gain used to analyse disturbance attenuation performance systems, weighted obtained under bounded exogenous disturbances. Then, problem non-autonomous systems solved. All proposed formulated in programming. Finally, two illustrative examples...

Camellia oleifera (C. oleifera) is one of the four major woody oil-bearing crops in world and has relatively high ecological, economic, medicinal value. Its seeds undergo a series complex physiological biochemical changes during ripening, which mainly manifested as accumulation transformation certain metabolites closely related to oil quality, especially flavonoids fatty acids. To obtain new insights into underlying molecular mechanisms, parallel analysis transcriptome proteome profiles C....

Theranostics is a new type of biomedical technology that organically combines the diagnosis and therapy diseases. Among molecular imaging techniques, integration photoacoustic (PA) fluorescence (FL) modes with high sensitivity depth provides precise diagnostic outcomes. Gold nanorods (Au NRs) are well-known contrast agents for PA photothermal therapy. However, their toxicity, poor biocompatibility, rapid clearance, need an external laser source limit application. Therefore, modification Au...

This paper investigates the problem of optimizing transmission schedule between a sensor and relay in cyber-physical systems to achieve accurate remote state estimation. The considered system model represents plant as linear time-invariant system, wherein measurements are transmitted estimator using an intelligent relay. Both nodes capable harvesting energy from external environment, they required make decisions at each time step ensure stability system's operation. In addition, sharing...

The optimal control of state‐of‐charge (SOC) for superconducting magnetic energy storage (SMES), which is used to smooth power fluctuations from wind turbine, essential improve its technical and economical performance. Without an efficient strategy, the SMES may go state over‐charge or deep‐discharge, will pose a significant effect on service life In this study, combined with forecasting technology real‐time monitoring SOC SMES, double fuzzy logic strategy proposed that applied regulate...

This study investigates the feedback control for a class of switched positive linear systems (SPLSs). By means programming approach, output‐feedback and state‐feedback controllers underlying with average dwell time are designed, respectively. Under these controllers, closed‐loop asymptotically stable. These results obtained provide way to solve synthesis problems SPLSs by multiple copositive Lyapunov functions. Finally, an example is given illustrate validity present design.
