An industrial plant has hundreds or even thousands of control loops. The performance of control loops is important to ensure high product quality and low cost of the product in such plants. In general, oscillatory variables are one of the main causes for poor performance of control loops. Therefore, detection and diagnosis of the causes of oscillations in control loops is very vital for maintaining the product within the desired quality limits. Identification of such source signatures is a very important task in assessing closed loop control pe ....etc

ABSTRACT

In recent years, mining of sequential patterns has been studied extensively in various domains. Most of the existing algorithms find patterns in transactional databases by scanning the records whether they contain patterns or not. This paper proposes a novel algorithm to mine closed sequential patterns using an inverted matrix and prefix based sequence element matrix. Inverted matrix minimizes the search space ....etc

Wireless based Automatic dam water level control shutter open /closed with emergency information System
ABSTRACT
In this project to maintain the dam water level. it s very use full for emergency time every information is going though control area so easily identify the dam information if the dam water level will be high the shutter automatically open depending upon the water level. The information is going though the particular person here we have used RF wireless communication ....etc

Closed loop timing



Bundled closed loop timing

Signal AD and ref signal Aclk transition tncq after each transition on Tclk
Vector BD and reference Bclk transition tnAB later.
Timing loop locks the quadrature clock Qclk to Bclk with offset lag equal to aperture offset ta0 of phase detector of flip-flop
This places the receive clock, Rclk which is offset from Qclk by /2
Aperture is exactly centred on the eye of data vector BD.

Which of these elements of timing uncertainty are cancelled?

applications of microcontroller based automatic door open and closed system using ir sensor pdf

This is a good Electronics Project report on Automatic Door Opening System Using IR Sensors which is used to automate door opening. Some of the main component required for this project are Power supply, ATMEL (AT89S52)Microcontroller, Stepper Motor & IR sensors. This report start with the introduction to embedded systems. In this system whenever the infrared sensor senses the obstacle and the signal is sent to the microcontroller. Then the microcont ....etc

ABSTRACT

Ceiling fan operation control for tuning the fan on and off based on a passive infrared sensor, combined with a temperature sensor to regulate the speed of the fan. The passive infrared sensor, the temperature sensor and controls for both are in a housing directly mounted to the fan motor of the ceiling fan. The controls can be set screws covered by a removable cap. The passive infrared sensor can include a fresnal lens for sensing a 360 degree circumference beneath the fan, and a photo-optical sensor such as a photocell, which suspen ....etc

Open loop control vs. closed loop (feedback) control



The next two figures present the structures of open loop and feedback control systems.
Figure 1 shows an open loop control system whose function is to cause the output y(t) to follow the
reference r(t).
Feedback control system design for zero steady state error
In general, to follow a reference R(s) with zero steady-state error, the path between the
reference and the system output should contain a term like R(s). For instance, to follow a ramp
