This paper is concerned with a class of discrete-time nonhomogeneous Markov jump systems multiplicative noises and time-varying transition probability matrices which are valued on convex polytope. The stochastic stability finite-time considered. Some criteria including infinite matrix inequalities obtained by parameter-dependent Lyapunov function. Furthermore, converted into finite linear (LMIs) via set slack matrices. Finally, two numerical examples given to demonstrate the validity...
This paper studies a discrete‐time stochastic LQ problem over an infinite time horizon with state‐and control‐dependent noises, whereas the weighting matrices in cost function are allowed to be indefinite. We mainly use semidefinite programming (SDP) and its duality treat corresponding problems. Several relations among stability, SDP complementary duality, existence of solution algebraic Riccati equation (SARE), optimality established. can test mean square stabilizability solve SARE via by...
The problem of finite time adaptive control for stochastic nonlinear system is studied in this paper, where the has a non-strict feedback structure. Under sense stability, authors propose new neural network (NN) controller systems by backstepping technique. To overcome difficulties that arise from structure system, key lemma introduced. All signals closed-loop are bounded probability under controller. At same good tracking performance can be achieved. A simulation example further shows...
At the end of 2019, COVID-19 started to rage and vaccine became most effective solution. triggered a high level attention from social media. twitter one main platforms for public post their attitudes tendencies towards vaccine, providing text corpus opinion research based on sentiment analysis. In this paper, we use Twitter posted between August 2020 2021 as information base. We BiLSTM with Attention Mechanism algorithm calculate value data, then temporal spatial dimensions mine topics users...
This paper focuses on the design of H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</sub> control for T-S fuzzy systems with input time-varying delay via dynamic output feedback. Based recently developed reciprocally convex approach, some less conservative delay-dependent sufficient conditions existence controllers are given in terms linear matrix inequalities(LMIs). Finally, a practical example is provided to show advantages and...
This paper studies the output feedback stochastic linear quadratic (LQ) optimal control with state and dependent noise. Firstly, some necessary/sufficient conditions for static stabilizability are given. Secondly, infinite horizon dynamic LQ studied, respectively.
This article is based on the remote acceptance requirements of power supplies and relies image recognition algorithms in artificial intelligence to propose a batch standardized LSTM automatic identification method for status supplies. It achieves intelligent whether outer packaging intact goods themselves are damaged. The experiment shows that proposed this can improve efficiency material while achieving status, effectively support implementation on-site scenarios.
This paper is concerned with a discrete‐time indefinite stochastic LQ problem in an infinite‐time horizon. A generalized algebraic Riccati equation (GSARE) that involves the Moore‐Penrose inverse of matrix and positive semidefinite constraint introduced. We mainly use semidefinite‐programming‐ (SDP‐) based approach to study corresponding problems. Several relations among SDP complementary duality, GSARE, optimality are established.
