Due to the difficulties arising in state estimation in Model Predictive Control (MPC) algorithms, Kalman filtering and dynamic matrix control (DMC) estimation approaches were combined in the current work. Then a weighting average of both estimated states was passed to the algorithm. To determine the weighting coefficient of the mentioned average, a fuzzy supervisor was designed to control the c...

This work addresses the problem of spatial reference estimation in mobile scenarios. Novel techniques based on fuzzy logic are introduced to enhance the performance of a trackmg system. Specifically, the model-free function approximation capability of fuzzy logic is used to obtain high resolution angle estimates from the spatial spectral density. These estimates are used to improve the resoluti...

Supervisor localization can be applied to distribute a monolithic supervisor into local supervisors. Performing computationally costly. In this work, we consider systems that evolve over time. We study how reuse the results from previous localization, more efficiently compute supervisors when system is adapted. call approach transformational and present algorithms for procedure. The efficiency ...

A fuzzy controller equipped with an adaptive algorithm and two supervisors is developed in this work to achieve tracking performances for a class of uncertain nonlinear single input single output (SISO) systems with external disturbances. The convergence of the training algorithm is guarantied by a gradient projection law. The effect of both the approximation errors and the external disturbance...

2 on the H performance level, while satisfying the H performance. The proposed hybrid control scheme is based on a fuzzy supervisor which manages the combination of two controllers. A convex LMI-Based formulation of the two fast and slow subsystem controllers leads to a structure which ensures a good performance in both the transient phase and the steady state phase. The stability analysis uses...

background: nowadays job stress is one of the most important health problems that health and safety professionals are facing with. much of previous studies have focused on interventions such as stress management and, they have ignored the role of psychosocial factors in occurrence of job stress. this study investigated the mediator role of supervisor support on the association between work stre...

There is a growing need to understand how mobile devices are used to reach people in a crisis. This study focuses on how work organizations play a gatekeeping role in how their employees receive crisis information. Relying on research in the digital divide and organizational justice, this study compares two different types of organizations and their policies banning or allowing mobile devices a...
