For a world where energy demand is increasing day by day, available resources are constantly decreasing. At this point, it very important to be able benefit from the sun, which main source, with minimum damage environment. It possible produce electricity directly sunlight through PV panels. Due limited efficiency of these panels, MPPT algorithms always required. In study, Sliding Mode Control (...

The classical buck converter is a very common DC–DC converter, which reduces an higher input supply voltage to lower output load voltage. Replacing the inductor and capacitor by transmission line, we obtain distributed can be described partial differential equations. Therefore, completely new class of model. This topology used if operated at some spatial distance from power supply, where line d...

This paper presents the movement dynamic of the train and the relationship between the speed of wheel and train, as well as a discussion about the concept of wheel slip. There are two different operation regions designated as creep and wheelspin areas for wheel slip. Creep and wheelspin areas have stable and unstable characteristics, respectively. Wheels and rails are constructed from iron, and...

In this paper we consider a linear discrete-time control system affected by an additive sinusoidal disturbance with known frequencies but unknown amplitudes and phases. The problem is to damp this forced oscillation in an optimal fashion. We show that the natural solution from the point of view of optimal control is neither robust with respect to errors in the frequencies, and thus not optimal ...

We formulate a discrete time model to identify and evaluate the role of optimal control strategies on influenza transmission. We divide the population in two subgroups defined according to the contact activity or susceptibility levels. The individuals are identified as susceptible, infectious, treated, and recovered. The potential effect of antiviral treatment considering unlimited and limited ...

Since GPS technology which is intensively used in surveying application today, can not directly be employed to measure some details such as building boundaries, it is still a necessity to establish control points on the ground and coordinate them by GPS and then measure the details by a total station set up on these control points. Establishment of control points on the ground and their compuls...

SCPS is a novel self-configuring power-saving protocol for wireless one-hop ad hoc networks. According to IEEE 802.11 WLAN standard, a station may enter a special power-saving (PS) mode. SCPS allows all stations in the PS mode to adjust their wakeup schedules whenever a station enters or exits the PS mode. The adjustment can balance the number of wakeup stations in each beacon interval so that ...

The throughput performance of a random cooperative medium access control (CoopMAC) network in the presence of shadowing is considered. The nodes are assumed to be randomly distributed according to a homogeneous twodimensional Poisson point process with constant intensity. The conditions under which a helper can improve the transmission rate between a given pair of nodes are examined. Based on t...

This paper presents the mini-max bound on the width of the admissible control point band of the shape coding algorithms. It also proposes to use an accurate distortion measure instead of the tolerance band.

In this paper, we develop a new control technique for discrete event dynamic systems subject to synchronization phenomena. We propose a feedback controller for (max,+)-linear systems which delays input events as little as possible while constraints on internal or output events are satisfied. The synthesis is mainly based on new results about fixed points of antitone (i.e., order reversing) mapp...
