This article proposes an adaptive coordinated control strategy for the networked AC/DC microgrids (MGs) to enhance frequency and dc voltage stability of system while keeping proper power sharing. First, a based on synchronverter virtual machine (VDCM) converters connecting AC DC MGs is proposed, which consisted governor inertia regulator besides sharing controller. Following, in order performan...

This paper presents fuzzy and conventional performance of model reference adaptive control(MRAC) to control a DC drive. The aims of this work are achieving better match of motor speed with reference speed, decrease of noises under load changes and disturbances, and increase of system stability. The operation of nonadaptive control and the model reference of fuzzy and conventional adaptive contr...

One of the most challenging control problems has been speed an alternating current (AC) motor due to highly nonlinear characteristics and many uncertain parameters including magnetic flux, temperature-dependent rotor resistance, variable load. In this study, intelligent algorithm is proposed for AC using a PID controller-based backpropagation neural network (BP-NN). The momentum factor adaptive...

Driven by carbon-neutral targets and transportation electrification, the widespread use of electric vehicles (EVs) has become an irreversible trend. However, low-voltage distribution networks (LVDNs) can face several challenges under high-penetration EV integration, including overloads, voltage violations unbalance issues. In this paper, integration-oriented DC conversion scheme associated adap...

This paper includes modeling and simulation of 180 MW units of pumped storage power plant with Variable speed machines. In this method, voltage source inverters are used instead of traditional cyclo-converters. This paper aims to control the voltage source inverters and maintain DC voltage at a constant value. AC/ DC/ AC converter is used in system configuration structure in order to control an...

This paper considers the design of an observer-based adaptive controller for variable speed threephase AC induction motors. The proposed controller allows for the simultaneous and independent control of the speed (torque) and the flux of the motor without requiring the measurement of the flux, and without the knowledge of the rotor resistance and the motor load. The control adaptively estimates...

This paper discusses an adaptive control (AC) designed to track an energy-saving point-to-point (ESPTP) trajectory for a mechatronic system, which is a toggle mechanism driven by a permanent magnet synchronous motor (PMSM) with a clamping unit. To generate the PTP trajectory, we employed an adaptive real-coded genetic algorithm (ARGA) to search for the energy-saving trajectory for a PMSM-toggle...

The AC-excited hydrogenerator (ACEH) is a novel type of hydraulic generation system. Concern about its integrative control strategy is increasing, owing to the features of uncertain and nonlinear as well as parameters coupling and time-variation for three parts of water flux, hydroturbine and generator. A cascade-connected self-adaptive fuzzy-neural network control strategy is proposed, which t...

Adaptive oblivious transfer (OT) is a protocol where sender initially commits to database {Mi}i=1N. Then, receiver can query the up k times with private indexes ρ1,…,ρk so as obtain Mρ1,…,Mρk and nothing else. Moreover, for each i∈[k], receiver's choice ρi may depend on previously obtained messages {Mρj}j<i. Oblivious access control (OT-AC) flavor of adaptive OT records are protected by distinc...

This paper presents the design and experimental implementation of an L1 adaptive control on a tethered underwater vehicle. This controller, well known for its fast adaptation and its robusntess, is proposed to be applied for the first time in the field of underwater vehicles control. This paper summarizes the implementation and experimental results obtained on a modified version of the AC-ROV u...
