in this paper, the unified power flow controller (upfc) is enhanced with a chaotic particle swarm optimization (cpso) damping controller in order to mitigate the low frequency oscillations (lfo) in a single machine infinite bus (smib) power system. the designed damping controller is an optimized lead-lag controller, which extracts the speed deviation of the generator rotor and generates the out...

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...

87 Abstract Based on the novel rotor speed control, the complete AC/DC/AC synchronous machine drive system is integrated. It consists of AC grid, rectifier, inverter and synchronous machine with its excitation system. All power components as well as complete control system are modeled. The sequences of machine starting, voltage control and reactive power control are then accomplished. Short cir...

Although adaptive control (AC) systems for machine tools have a tremendous potential for improving productivity in manufacturing, their acceptance by industry has been slow. This paper identifies the major research and development areas for AC machine tools, and summarizes the principal developments of the last two decades. Current research at The University of Michigan, which is aimed at the d...

We describe an abstract machine, called GcPan, for the distributed execution of Safe Ambients (SA), a variant of the Ambient Calculus (AC). Our machine improves over previous proposals for executing AC, or variants of it, mainly through a better management of special agents (forwarders), created upon code migration to transmit messages to the target location of the migration. We establish the c...

The neurally inspired accumulative computation (AC) method and its application to motion detection have been introduced in the past years. This paper revisits the fact that many researchers have explored the relationship between neural networks and finite state machines. Indeed, finite state machines constitute the best characterized computational model, whereas artificial neural networks have ...

In this paper, a synchronous/permanent magnet hybrid(SynPM) machine is presented. It is shown that the machine has good power density and efficiency, and that the machine has true field regulation capability. The principle of operation, finite element analysis and simulation of this new machine are investigated in the paper.

In a practical alternating current (ac) machine drive system, zero-order hold equivalent discrete-time model motivates the development of direct regulator structure. However, it is complicated to establish for asymmetric 1 <fn id="fn1" xmlns:xlink="http://www...

A note on practical experience with on Aho-Corasick-machine and SNFA (Searching NFA) estimating the construction aspects and run cost. It is shown that SNFA can be more practical than AC-machine.
