We demonstrate control on nonadiabatic molecular alignment by using a spectrally phase-shaped laser pulse. An evolutionary algorithm in a closed feedback loop has been used in order to find pulse shapes that maximize a given effect. In particular, this scheme has been applied to the optimization of total alignment, and to the control of the temporal structure of the alignment transient within a...

There are many power electronic converters and motor drives connected together to form the electrical system of an elevator. In this paper, we have presented a modeling tool that has the advantages of utilizing capabilities of the PMSM software in detailed simulations of converters, motor drives, and electric machines. In addition, equivalent electrical models of Elevator drive system. This pap...

As part of the pre-conceptual design activities for European DEMOnstration plant, a carefully selected set safety analyses have been performed to assess plant integrated performance and capability achieve expected targets while keeping it in safe operation domain. The DEMO divertor is in-vessel component charge exhausting major plasma ions’ thermal power region far from core control pollution. ...

This paper presents a new approach to the intrastream synchronization problem. The proposed technique is based on controlling the receiver buffer. The basic idea is to find realistic models for the control loop components and to apply automatic control methods to choose an appropriate control algorithm and to derive stability criteria and transient behavior of the whole system. The theoretical ...

The scaling of transient times to zero-lag synchronization in networks composed of excitable units is shown to be governed by three features of the graph representing the network: the longest path between pairs of neurons (diameter), the largest loop (circumference) and the loop with the maximal average out degree. The upper bound of transient times can vary between O(1) and O(N), where N is th...

The possibility of achieving a deadbeat regulation and tracking in linear systems independently of their initial conditions is investigated. The attention is focused on single-input single-output control systems incorporating a dynamical sensor in the loop. A necessary and sufficient condition for a deadbeat controller to exist is established. All deadbeat controllers are described in paramet­ ...

Design and evaluation of dynamic model of multi-input/multi-output power converter consisting of six converters connected by dc-link will be presented in the paper. The model was created in Matlab/Simulink based on the existing system, with the goal of evaluating various power management strategies, where only transient behavior in case of changed operating regime is of interest. In future the ...

In this paper, a parallel AC/DC power system is investigated, and a nonlinear robust controller is proposed to improve transient stability of the power system and to damp out any prolonged oscillation after a fault is cleared. Lyapunov’s direct method is used to synthesize the control, and asymptotic stability of the closed loop system and improved dynamic performance are shown by both theoreti...

This paper deals with a control technique of eliminating the transient vibration of a waist axis of an articulated robot. This technique is based on a model-based control in order to establish the damping effect on the mechanical part. The control model is related to the velocity control loop, and it is composed of reduced-order electrical and mechanical parts. Using this model, the velocity of...

In this paper an exact transient analysis of Bang-Bang PLLs (BBPLLs), as a nonlinear system, is presented. New equations are proposed for expression of transient behavior of the BBPLL with first order filter in response to phase step input. This approach gives new insights into the transient behavior of BBPLLs. Approximating transient response to reasonable specific waveform; the loop transient...
