Model Based Selection of an Appropriate Control Strategy Application to an Anaerobic Digester

Abstract: The aim of this work is to develop an integrated control of anaerobic digesters in wastewater treatment plants, to ensure optimal depollution performances. To achieve this goal, we have to summarise our knowledge in a mathematical model, which is an essential tool for control design.Various control strategies can be chosen, but their performances are very different (stabilisation, biogaz production,F F F). Each of them is evaluated through 3 criteria. Then we present an original linear model for process stabil… Show more

“…For small overloads, the process remains on the attraction region associated to the functioning point and it crosses over the stability limit if the overloads reach larger amplitudes. From this analysis it is possible to conclude that anaerobic digestion can reject small disturbances by itself, but it requires a control action in order to avoid washout in presence of large disturbances [38].…”

“…Selama proses pembentukan dari biogas tersebut bioreaktor sangat rentan terhadap perubahan suhu, substrat yang tidak stabil, dan juga pH [1]. Variabel tersebut perlu diperhatikan supaya mikroorganisme yang ada didalamnya tidak mengalami washout (matinya mikroorganisme yang mengakibatkan bioreaktor tidak dapat diolah lagi, dan memerlukan waktu pemulihan yang cukup lama supaya dapat digunakan kembali) [2].…”

“…Banyaknya variabel yang berpengaruh dalam pembentukan biogas menjadikan bioreaktor sulit untuk dilakukan monitoring kondisinya. Dari hal tersebut nantinya akan digunakan logika fuzzy untuk mengolah data supaya dapat menentukan keadaan yang terjadi pada bioreaktor berdasarkan parameter yang diukur dan hasil pembacaan akan ditampilkan pada GUI beserta output tegangan dari setiap sensor yang digunakan [2].…”
