Observability and Identifiability Analyses of Process Models for Agricultural Anaerobic Digestion Plants
Simon Hellmann, Arne-Jens Hempel, Stefan Streif +1
Dynamic operation of anaerobic digestion plants requires advanced process monitoring and control. Different simplifications of the Anaerobic Digestion Model No. 1 (ADM1) have been…
Modeling and optimal control of growth, energy, and resource dynamics of Hermetia illucens in mass production environment
Murali Padmanabha, Alexander Kobelski, Arne-Jens Hempel +1
Mass production of Hermetia illucens insect larvae is now being adopted in many countries and is taking an industrial production approach. Despite abundant literature on factors th…
Process Optimization of Black Soldier Fly Egg Production via Model Based Control
Alexander Kobelski, Arne-Jens Hempel, Murali Padmanabha +2
Black soldier fly (BSF) larvae (\textit{Hermetia illucens}) are a valuable protein source for manufacturing animal feed. To maximize their production, both the quantity and quality…
High-gain observer for the nitrification process including sensor dynamics
Patrick Schmidt, Arne-Jens Hempel, Stefan Streif
Fertilization is commonly used to increase harvests. The lack of knowledge of soil properties and the excessive use of fertilizers can result in overfertilization. Current sensor t…
On the Turnpike to Design of Deep Neural Nets: Explicit Depth Bounds
Timm Faulwasser, Arne-Jens Hempel, Stefan Streif
It is well-known that the training of Deep Neural Networks (DNN) can be formalized in the language of optimal control. In this context, this paper leverages classical turnpike prop…
A comprehensive dynamic growth and development model of Hermetia illucens larvae
Murali Padmanabha, Alexander Kobelski, Arne-Jens Hempel +1
Larvae of Hermetia illucens, also commonly known as black soldier fly (BSF) have gained significant importance in the feed industry, primarily used as feed for aquaculture and othe…
Prototypical Description and Controller Design for a Set of Systems Using v-gap Based Clustering
Lukas Munser, Arne-Jens Hempel, Grigory Devadze +1
We present an approach to design stabilizing controllers for a set of linear systems without restrictions regarding their modeling order. To this end, the systems are treated as ab…
Half-Gain Tuning for Active Disturbance Rejection Control
Gernot Herbst, Arne-Jens Hempel, Thomas Göhrt +1
A new tuning rule is introduced for linear active disturbance rejection control (ADRC), which results in similar closed-loop dynamics as the commonly employed bandwidth parameteriz…
