Kablosuz Ağ Uygulamaları ile Dirençli Hata Kontrolünün Sıvı Seviyesine Etkisi

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

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.
