- The adaptive autopilots are based on velocity scheduling, a self-tuning regulator for steady state course keeping, a high gain turning regulator with variable structure, and a Kalman filter. Results from simulations and full-scale experiments on three different tankers are presented. The autopilots are shown to work excellently under different loads, speed and weather conditions.

Estimation and Control of Biological Activity in the Activated Sludge Process Using Dissolved Oxygen Measurements
- 1977

Ingår i: IFAC Symposium on Environmental Systems Planning, Design and Control, Kyoto, Japan, 1-5 August. - 1474-6670. ; 10:7, s. 745-755

Konferensbidrag (refereegranskat)abstract
- The control of an activated sludge process is considered. It is discussed how the organism activity is a crucial information for the control. It is shown, how the concentration profile of dissolved oxygen (DO) in the biological reactor is related to the sludge activity. As a result the DO profile is a useful measurement information for control purposes
