This paper is concerned with an uncertainty and disturbance estimator-based tracking control problem for a class of interval type-2 fractional-order Takagi-Sugeno fuzzy systems subject to time-varying delays. The footprints the underlying are taken into account capture model different levels uncertainties. estimator used promote behavior rejecting in system. First, by applying Lyapunov approach...

state estimation is the foundation of any control and decision making in power networks. the first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. this paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...

In this study, the fuzzy-based reference flux estimator (RFE), torque (RTE) and sector rotation strategy called fuzzy logic are proposed to direct control of induction motor (DTC-IM) drive for performance improvement. The basic DTC-IM with conventional RFE, RTE division causes large ripple, variable switching frequency uneven voltage vector contribution in stator flux. speed responses system in...

Let be a random sample from a normal distribution with unknown mean and known variance The usual estimator of the mean, i.e., sample mean is the maximum likelihood estimator which under squared error loss function is minimax and admissible estimator. In many practical situations, is known in advance to lie in an interval, say for some In this case, the maximum likelihood estimator...

Estimation of the size and time required for software development is probably the most difficult task of software projects development. Functional Point Analysis (FPA) model are gaining a wide popularity for assessing software size. By the definition of Function Point Analysis model, all 14 General System Characteristics (GSC) are not totally independent. A fuzzy neural network model for tuning...

Mining typical user profiles and URL associations from the vast amount of access logs is an important component of Web personalization. In this paper, we define the notion of a “user session” as being a temporally compact sequence of Web accesses by a user. We also define a dissimilarity measure between two Web sessions that captures the organization of a Web site. To cluster the user sessions ...

This paper presents a stable new algorithm for force/position control in robot manipulators. In this algorithm, position vectors are measured by sensors and then used in the control law. Since using force sensor has some issues such as high costs and technical problems, an approach is presented to overcome these issues. In this respect, force sensor is replaced by an adaptive fuzzy estimator to...

This article presents a novel fuzzy–logic based multi-sensor data fusion algorithm for combining heading estimates from three separate weighted interval Kalman filters to construct a robust, fault-tolerant heading estimator for the navigation of the Springer autonomous surface vehicle. A single, low-cost gyroscopic unit and three independent compasses are used to acquire data onboard the vehicl...
