An unhealthy condition of a biogas reactor is an abnormal situation characterized by a large reduction of the concentration of the microorganisms in the reactor, causing a reduction of the biogas production. This condition may occur due to too high f

A modification of the PI setting of the Ziegler-Nichols closed loop tuningmethod is proposed. The modification is based on a combination of the Skogestad SIMCtuning formulas for ''integrator plus time-delay'' processes with the Ziegler-Nichols tuning

This paper is about position control of a specific small-scale pilot underwater lifting body where the lifting force stems from buoyancy adjusted with an air pocket in the lifting body. A mathematical model is developed to get a basis for a simulator

A state estimator and various model-based control systems have been designed for a real anaerobic digestion (AD) pilot reactor fed with dairy manure. The model used is a modified Hill model which is a relatively simple dynamical AD process model. The
