This paper studies the problem of stabilization for an interval type-2 Takagi-Sugeno-Kang fuzzy logic control system (IT2 TSK FLCS) with time varying delay. A type-1 fuzzy system (T1 FS) is used for modeling the plant, then an interval type-2 fuzzy system (IT2 FS) is used for constructing the controller which has been realized better abilities to handle uncertainties than its T1 counterpart. A less-redundant...
This paper presents a novel fault diagnosis approach based on the reset observer to improve the rapidity as well as the accuracy of fault diagnosis. By introducing an integral reset mechanism into a traditional observer, the reset observer overcomes the linear fundamental limitations and can decrease the overshoot and settling time simultaneously in the estimation process. In this paper, an augmented...
This paper concerns with the problem of adaptive observer-based fault estimation of linear multi-agent systems with actuator faults. An undirected multigraph is used to represent the communication topology of a group of leader-follower vertical takeoff and landing (VTOL) aircrafts, and one method of fast adaptive fault estimation (FAFE) using relative output estimation error is proposed to achieve...
This paper focuses on sensor fault estimation problem for nonlinear singularly perturbed systems with bounded disturbances. The considered fault signals can be unbounded. An observer which satisfies a prescribed H∞ performance index is presented to evaluate the system states and fault signals simultaneously. Sufficient conditions for the existence of the presented observer is derived in the form of...
This paper investigates the distributed adaptive event-triggered consensus control for a class of Lipschitz nonlinear agents. Each agent is subject to input saturation. Two kinds of distributed event-triggered control scheme are introduced, one is continuous-time based event-triggered scheme and the other is sampled-data based event-triggered scheme. Compared with the traditional event-triggered schemes...
