Reglering av sackaroshalten vid fermentation i en reaktor med kontinuerligt flöde
Fermentation in a 5 l continuous flow reactor with immobilized yeastcells is controlled. Substrate concentration (sucrose) is continuosly measured with an enzyme thermistor. The control variable is flowrate through the reactor. The main controlproblem is a timelag in the measurementsignal. A bilinear processmodel is formulated and used for design of different controllers. Comparison is done betwee

Automatic Tuning of a KaMeWa Waterjet servo
A water jet is a propulsion system for vessels. The principle of water jet is to admit water into the hull, then add head to the water via the impeller and then let the water go through a guide vane package and then discharge it at the stern. The reaction force will bring the vessel into motion. KaMeWa Group, a Vickers company who manufactures water jet propulsion systems, initiated the work. This

Automatisk viktreglering av ubåt med olinjära systemkomponenter
This is a presentation of automatic weight control of a submarine, where the use of nonlinear system components has been considered. The work was done at Lund Institute of Technology, Department of Automatic Control, with Kockums Marine, Malmö as sponsoring organization. The nonlinearities are due to the use of OnOff pump in the controller. This presentation consists of five different controllers.

Studie av regulatorer för elektrohydauliska lägesservon
The purpose of this thesis has been to study different types of control strategies for an Electrohydraulic position servo in a Fuel metering valve. The Servo needs a high accuracy and fast response controller. Unlinearlities cause the system dynamics to vary with different operating conditions. A mathematical model implemented in the simulation tool ACSL is used in design and analysis. The System
