Accurate torque control is of interest in traction and other industrial applications, whose realization challenged by parameters errors temperature-induced variations. This article proposes a sensorless technique for resilient salient synchronous machines. The position observer driven the adaptive projection vector error estimation (APP) scheme. A second vector, orthogonal to APP noninterferenc...

This paper deals with state estimation of micro tunable capacitor subjected to nonlinear electrostatic force. For this end a nonlinear observer has been designed for state estimation of the structure.  Necessary and sufficient conditions for construction of the observer are presented. Stability of the observer is checked using Lyapunov theorem. Observer design is based on converting of differen...

accurate interpretation of radiographic images is dependent on viewing conditions. recently the number of radiology departments has been increased so it needs to use a workstation for reporting. the aim of this study was assess monitor performance and the effect of viewing conditions on object detection. this investigation aimed to quantify the effects of changes in box brightness and ambient l...

In this article, a cyber-resilient consensus-based distributed control scheme is proposed for islanded ac microgrids. Considering the impacts of false data injection (FDI) attacks on conventional consensus algorithms, hybrid solution presented based combination multiobjective sliding-mode and communication link quality observer to provide reliable performance against different types FDIs. Unlik...

The state estimation of a quantized system (Q.S.) is a challenging problem for designing feedback control and model-based fault diagnosis algorithms. The core of a Q.S. is a continuous variable system whose inputs and outputs are represented by their corresponding quantized values. This paper concerns with state estimation of a Q.S. by a qualitative observer. The presented observer in this pape...

In the current competitive and dynamic market, customer demands and interests are changing continuously, and hence, risk of disruption in the supply chain is also increasing. To be successful in this scenario, supply chain of a firm should be resilient. Most of the firms realize that with a specific end goal to develop a resilient supply chain, there is a need for assessment of performance. The...

In this paper, an observer based fuzzy adaptive controller (FAC) is designed fora class of large scale systems with non-canonical non-affine nonlinear subsystems. It isassumed that functions of the subsystems and the interactions among subsystems areunknown. By constructing a new class of state observer for each follower, the proposedconsensus control method solves the problem of unmeasured sta...
