In this paper various methods for the designing of centralized PI controller for desalination system and distillation columns given in the literatures are discussed. Various tuning methods given by Davison and Maciejowski are used. The performance of the closed loop system servo responses are compared of terms of ISE. The better controller tuning method is chosen by means of least ISE value. IN...

In [3] D. Bar-Natan and S. Garoufalidis used a weight system for the Alexander polynomial of knots to prove the so-called Melvin–Morton–Rozansky conjecture [18, 21] which relates the Alexander polynomial and some coefficients of coloured Jones polynomial. Their weight system can be easily extended to the case of links. It is a natural problem to give a weight system for the multivariable Alexan...

This paper presents a new control-loop configuration criterion for multivariable processes. Both the steady-state and transient information of the process transfer function are investigated. A new interaction measurement, relative normalized gain array, is proposed for evaluating control-loop interactions. Consequently, a new loop pairing criterion based on the relative normalized gain array is...

A Multivariable Control System is designed for an Electromagnetic Bearing and Rotating Shaft System. The Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) methodology is used to design a robust Model Based Compensator (MBC). The electromagnetic bearing consists of an electromagnetic actuator, operated in magnetic "attractive" force mode, with permanent magnet biased coils. The per...

In an industrial boiler system, multiloop (decentralized) proportional-integral (PI) control is used because of its implementational advantages. We show that such control schemes sacrifice robustness and performance of the overall system. In particular, under normal boiler operating conditions, we design a robust multivariable controller using loop-shaping techniques; for consideration in imple...

The emergence of wireless sensor network as has raised the need for cheap wireless indoor localization technique This paper considers the problem of fingerprinting indoor localization based on signal strength measurements RSS. A new approach based on Fuzzy logic has been put forward. The proposal makes use of k-nearest neighbor classification in signal space. The localization of target node is ...
