This paper present a pulse width modulation non-isolated buck converter using PID controller. The buck converter constituted by one Gto, one inductor, one capacitor, one diode and one load resistor. In this the buck converter connected to the PID controller, PID controller calculate an error value as the difference between a measured process variable and a desired set point. The proportional P ...
The purpose of this paper is to present a new adaptive control method used to adjust the output voltage and current of DC-DC (DC: Direct Current) power converter under different sudden changes in load. The controller is a PID controller (Proportional, Integrator, and Differentiator). The gains of the PID controller (KP, KI and KD) tuned using Simulated Annealing (SA) algorithm which is part of ...
Digital Signal Processing is used in many areas where analogue method was difficult. Filters are used to separate or combine different frequencies. In this paper low pass filter has been designed and simulated using different windows techniques. Hamming and Kaiser Windows techniques are used along with Rectangular window technique for the design analysis by using matlabs. The performances of al...
The azimuthal asymmetry of the minijet system produced in nucleon-nucleon and nuclear collisions in a central rapidity window is studied. We show that in pp collisions the minijet transverse energy production in a central rapidity window is essentially unbalanced in azimuth due to asymmetric contributions from one jet and two jet contributions. We show that at RHIC energy the distributions desc...
In this paper, an improved cascade control methodology for superheated processes is developed, in which the primary PID controller is implemented by neural networks trained by minimizing error entropy criterion. The entropy of the tracking error can be estimated recursively by utilizing receding horizon window technique. The measurable disturbances in superheated processes are input to the neur...
Transmission Control Protocol (TCP) is the transport-layer protocol widely used in the internet today. TCP performance is strongly influenced by its congestion control algorithms which limit the amount of transmitted traffic based on the estimated network capacity to avoid sending packets that may be dropped later. In other words Congestion Control is Algorithms that prevent the sender from ove...
In this paper, we present an analytical TCP model that takes into account of several issues that were ignored in the other existing models (such as those in [15], [19]), i.e., (i) the congestion window is not gradually decreased at the rate of w 2p 2 , but suddenly halved upon receipt of congestion indication and (ii) the congestion window is halved at most once during one roundtrip time (RTT)....
In the photolithography processing of semiconductor, line width is smaller and smaller. Therefore, the requirements of process window are stricter than before. In the small line width, the formation of serious white wall will affect line width and cause rejects in following process. The study conducted research on the control of best focus in which particularly explored the relationship between...
Critically ill patients often experience stress-induced hyperglycaemia, which results in increased morbidity and mortality. Glycaemic control (GC) can be implemented in the intensive care unit (ICU) to safely manage hyperglycaemia. Two protocols SPRINT and STAR, have been implemented in the Christchurch ICU, and have been successful in treating hyperglycaemia while decreasing the risk of hypogl...
Facing burst traffic, TCP congestion control algorithms severely decrease window size neglecting the fact that such burst traffics are temporal. In the increase phase sending window experiences a linear rise which may lead to waste in hefty proportion of available bandwidth. If congestion control mechanisms be able to estimate future state of network traffic they can cope with different circums...
