This paper develops a method of fuzzy observer-based H∞ reliable controller design for two-dimensional (2-D) discrete Takagi-Sugeno (T-S) fuzzy systems. The LMI-based conditions are proposed to guarantee an H∞ noise attenuation 7 of the whole system under both normal operation and in the presence of some actuator faults. Owing to the introduction of free matrices, the presented design method has a...
This paper investigates the fault detection observer design problem in finite frequency domain for two-dimensional (2-D) continuous systems in Roesser model. By the generalized KYP lemma, convex design conditions are obtained, which are expressed in terms of linear matrix inequalities (LMIs). An illustrative example is provided to demonstrate the feasibility and effectiveness of the proposed method.
In this study, the problem of simultaneous estimation of system states and disturbances is addressed for two-dimensional (2D) linear systems. The considered 2D systems can be described as Fornasini–Marchesini second local state–space model coupled with unknown disturbances in the measurement equation. Asymptotically stable and uniformly ultimately bounded integrated state/disturbance observers are...
This paper is concerned with asymptotic unknown input observers (UIOs) for two-dimensional (2-D) systems. A sufficient condition for the existence of the asymptotic UIO is given in terms of the rank conditions of the given system matrices. Based on this condition, a simple and effective method for designing asymptotic UIOs for 2-D systems is given. An example is also presented to illustrate the proposed...
