Abstract

Bu
yayında, kablosuz proses kontrolu için geliştirilmiş bir proses simülatörü ve
kablosuz iletişim uygulamaları için kullanılan antenler ve modüller
gösterilmiştir. İlk defa parametrik olmayan yöntemler ile belirlenen,oransal
integral türevsel ayarlama katsayıları kullanılarak dirençli hata kontrol
kodunun kablosuz sıvı seviye kontrol deneyleri üzerindeki etkisi araştırıldı.
Başlangıç kontrol edici katsayıları, kablosuz iletişimle bir basamak etki
değişimine yanıt olarak elde edilen verileri gösteren proses reaksiyon eğrisi
kullanılarak belirlendi. İyi ayarlanmış kontrol parametreleri bir MATLAB grafik
aracı (SISO) aracılığıyla değerlendirildi. Proses simülatörün öngerilim
değerlerini belirlemek için kontrol vanasının sabit açıklık derecesinde (% 10)
başlangıç kararlı hal elde edildi ve sistem çıkışı 100s boyunca izlendi. 100
saniyenin sonunda, MATLAB/Simulink blok diyagramındaki kontrol anahtarı
değiştirilerek kontrol algoritması etkinleştirildi ve sistemde farklı set
noktası değişiklikleri yapıldı ve aynı anda parametrelerin etkisi gözlemlendi.
İyi ayarlanmış parametreler ile dirençli hata kontrol kullanılarak farklı set
noktalarını takip etmek için yapılan kablosuz kontrol deneylerinde sıvı
seviyesinin istenen set değerlerinin etrafında düzelme eğiliminde olduğu
görüldü. Önerilen kablosuz kontrol ve iletişim ağı performansları, farklı sıvı
seviyeleri için hesaplanan hata karelerinin toplamı (ISE) ve hata mutlak
değerlerinin toplamı (IAE) değerleri ile karşılaştırıldı.

Impact of Robust Error Control on Fluid Level by Wireless Network Applications

Abstract

The paper presents a process simulator developed with wireless process control purpose and antennas and modules for wireless
communication applications. The impact of robust
error control code onwireless liquid level control experiments is investigated
by means of three tuning coefficients of the proportional integral derivative
actionswhich are initially determined by using non-parametric methods. The
initial controller tuning coefficients were determined using the process
reaction curve which sketched the data obtained in response to a step change by
wireless communication.  The well-tuned
control parameters were assessed by means of a MATLAB graphical tool (SISO). To
determine the bias values of the process simulator, an initial steady state was
obtained and the system output was monitored at the constant control valve
openness (10%) for 100s. At the end of 100 seconds, the control key in
MATLAB/Simulink block diagram was changed and the control algorithm was
activated and different set point changes were given to the system at the same
time and the effect of the parameters was observed. It was seen that the liquid
level tended to level off around the desired set values in the wireless control
experiments performed to follow different set points by using the wireless
robust error control with well-tuned parameters. The proposed wireless control and
communication networkperformances were compared with the integral of squared
error (ISE) and the integral of absolute error (IAE) criteria at various fluid
levels.
