Abstract

HCl üretim endüstrisinde atık su arıtma işleminde kullanılan pH nötralizasyonu prosesi sürekli frekans salınım yöntemi kullanılarak parametreleri ayarlanmış bir kontrol edici ile set noktasında kontrol edilmiştir. PID kontrol edici parametreleri için iki farklı PID ayarlama tekniği Ziegler-Nichols ve Tyreus-Luyben uygulanmış ve performansları karşılaştırılmıştır. Kimyasal prosesin doğrusal olmaması ve kararsızlığı nedeniyle, ayar noktasına ulaşmak için minimum oturma süresi, azaltılmış salınımlar, kısa yükselme süresi, ofseti ortadan kaldırma, minimum yüzde aşma, yüksek stabilite gürültü sinyalleri ve yük etkileri varlığında optimum ve istenen kontrol performansı elde edilmesi hedeflenmiştir. Elde edilen deneysel sonuçlardan, Oransal İntegral Türev (PID) denetleyicisinin farklı ayarlama yöntemleri için zaman alanı özellikleri hesaplanmıştır. Sonuçlar, Tyreus-Luyben ayar formülünün Ziegler-Nichols yöntemine kıyasla daha küçük set noktasına oturma süresi ve pik tepe aşım değerine sahip olduğunu göstermiştir.

INVESTIGATION OF THE EFFECT OF ADJUSTING CONTROL PARAMETERS WITH CONTINUOUS FREQUENCY OSCILLATION METHOD ON FEEDBACK CONTROL PERFORMANCE IN NEUTRALIZATION PROCESS

Abstract

The set point of the pH neutralization process used in the wastewater treatment process in the HCl production industry was controlled with a controller where the controller parameters were adjusted using the continuous frequency oscillation method. Two different PID tuning techniques, Ziegler-Nichols and Tyreus-Luyben, were applied for the PID controller parameters and their performances were compared. Due to the nonlinearity and instability of the chemical process, it is aimed to achieve optimum and desired control performance in the presence of minimum settling time, reduced oscillations, short rise time, elimination of offset, minimum percent overshoot, high stability noise signals and load effects to reach the set point. From the obtained experimental results, the time domain properties of the Proportional Integral Derivative (PID) controller for different tuning methods were calculated. The results showed that the Tyreus-Luyben tuning formula has a smaller set point settlement time and peak overshoot compared to the Ziegler-Nichols method.
