In this article, by use of sliding-mode control, a descriptor stochastic fuzzy system with time-varying delay is considered. First, a new sliding-mode surface is proposed. By use of it, the fuzzy system with different input matrices could be studied. At the same time, the controlled system still has strong robustness to external disturbance. Second, since time delay is variable, there is not the t...Show More
By use of the method of sliding-mode control, the stabilization of the T-S fuzzy stochastic system with time delay is considered in this article. The characteristic of the proposed method is that the input matrices of the fuzzy system are not common. And the proposed control method of this article can resist the disturbance. First, a novel sliding-mode surface is introduced. Using the new surface,...Show More
This article studies the sliding mode control (SMC) of a class of Takagi-Sugeno (T-S) fuzzy singular systems with matched external disturbances. The key advantage of this article is that the input matrices of the considered fuzzy systems could be different, and a novel SMC provided in this article has strong robustness. In this article, systems with delayed state are considered. The time delay is ...Show More
In this paper, a novel robust controller for continuous stochastic polynomial fuzzy systems is investigated. The aim of the proposed method is to eliminate the restrictive assumptions that the local input matrix Bi must be uniform and the sliding mode surface proposed did not consider the stochastic perturbations, which are required in most existing results. At the same time, the proposed method c...Show More
This paper studies a new scheduling problem in a steel plant, referring to continuous casting (CC), reheating furnace, and hot rolling (HR) processes, which is meaningful and important to the production efficiency and energy saving. First, the problem is modeled as a combination of two coupled subproblems: one assigns casts to continuous casting (CC) machines, decides sequence and start time for c...Show More
This paper investigates the problem of designing a robust controller for continuous polynomial fuzzy systems with external disturbances. The input matrix Bi(x) of the considered system is not equal to one another. To solve this problem, first, we rewrite every column vector of input matrix Bi(x) using the vectors of the basis matrix B(x). Second, by use of the column vector of B(x), the subsliding...Show More
In this paper, the stabilization problems for singular Markovian systems with Brownian motion are studied by use of sliding mode control (SMC) with the jumping transfer matrix known, unknown, or partly unknown. At first, a new stochastic sliding mode surface (SSS) is introduced. The problem of state trajectories moving among several sliding mode surfaces can be settled perfectly. By use of the pro...Show More
In this paper, the stabilization is investigated about fuzzy stochastic singular systems by the use of sliding-mode control (SMC). The advantage of this paper is that local input matrices of fuzzy systems could be different, and the SMC law provided in this paper still has strong robustness to resist external disturbance. In order to deal with the problem of different input matrices, a novel slidi...Show More
In this paper, the problem of sliding mode control (SMC) for mismatched uncertain system is investigated. Some delay dependent robust asymptotical stability conditions are provided. Firstly, we give a lemma. By this lemma, a delay-dependent sufficient condition is presented by means of linear matrix inequalities (LMIs) which makes sliding mode dynamics asymptotically stable. Secondly, an adaptive ...Show More
In this paper, a sum of squares(SOS) method is proposed to design observers for discrete-time polynomial fuzzy systems. The proposed SOS approach has two improved and innovative results for the existing linear matrix inequality (LMI) method to Takagi-Sugeno(T-S) discrete fuzzy observer designs. Firstly, a polynomial discrete fuzzy model is developed, which is a generation of the well-known T-S fuz...Show More
In this paper, a new adaptive control is proposed for uncertain nonlinear systems with state time delay. The uncertainties is approximately modeled by interval type-2 fuzzy neural networks. The proposed approach is based on the backstepping control technique. An adaptive interval type 2 neural fuzzy control is proposed for a class of uncertain nonlinear systems with unknown time delays. It is math...Show More
