The main objectives of vehicle motion control on an automated highway system are stable and safe automatic longitudinal and/or lateral path following in a platoon of vehicles. Various controllers can be used to satisfy the same objectives, but they may require different variables to be sensed or different conditions to be met. Supervision can select a controller and switch to a different contro...

Simulating the switching on of an overhead power transmission line (PTL) ultra-high voltage in a dead-end mode, containing significant aperiodic current component, both from switch control key and three-phase automatic reclosing (TARC) cycle, is performed using MATLAB software package. The aim modelling to search find optimal modes electrical operation terms admitting values component assessing...

This paper describes a four quadrant, 250kW(550V, 450A) switch-mode, zero current soft switching (ZCS) power converter for a 1.4 GeV beam transfer line magnet. The ZCS technique is the preferred approach for the high power switch-mode converters employing Insolated Gate Bipolar Transistors (IGBT) to reduce switching losses and EMI. This switch-mode power converter topology has been selected bec...

Switch-mode power supplies represent a particular class of variable structure systems (VSS). Thus, they can take advantage of non-linear control techniques developed for this class of systems. In this paper the so called sliding mode control is reviewed and its application to switchmode power supplies is discussed. Sliding mode control extends the properties of hysteresis control to multi-varia...

We analyze the quark spectral function above the critical temperature for deconfinement in quenched lattice QCD using clover improved Wilson fermions in Landau gauge. We show that the temporal quark correlator is well reproduced by a two-pole approximation for the spectral function and analyze the bare quark mass dependence of both poles as well as their residues. In the chiral limit we find th...

This paper addresses the problem of the fractional sliding mode control (FSMC) for a MEMS optical switch. The proposed scheme utilizes a fractional sliding surface to describe dynamic behavior of the system in the sliding mode stage. After a comparison with the classical integer-order counterpart, it is seen that the control system with the proposed sliding surface displays better transient per...

Component-Based Software Engineering has been introduced as a technique for the development of complex systems. Software complexity can also be reduced by partitioning the system behavior into different modes. Such a multi-mode system is able to change its behavior at runtime by switching between different operational modes. When a multimode system is developed by reusable software components, ...
