This paper is concerned with the design of a robust position Backstepping tracking controller for a permanent magnet synchronous motor (PMSM). A Backstepping control law is designed from the input-output linearization of the PMSM model, written in d-q coordinates. This controller is adapted via the estimation of the unknown load torque and friction effects. A linear extended state observer is devised...
The penetration of electric vehicles (EVs) has attracted growing research interests in its impact on both power and traffic networks. With the expansion of EVs' range as well as the development of fast charging technology and related infrastructure, large-scale EVs are involved in intercity transportation systems and power transmission systems. We propose a traffic-power integrated network model and...

This paper introduces a distributed energy management for islanded DC microgrids with electric vehicles (EVs) penetration. The energy management problem is divided into two stages. The first, named as filtering stage, is controlled through wavelet filter using the ultracapacitor. The second one is modeled as a noncooperative stackelberg game, where the battery energy storage system is designed as...
Load Frequency Control (LFC) for an islanded microgrid is so critical due to intermittent behaviors of load and renewable energies. Performance of PID controllers deteriorates under uncertainties necessitating a controller that specifically considers these uncertainties. A stochastic controller can count for these uncertainties and hence a self-tuning PID controller based on Hebbian Learning method...
