ESS, the European Spallation Source, will be a major user facility at which researchers from academia and industry will investigate scientific questions using neutron beams. ESS will deliver its protons to a solid, rotating tungsten target, which will in turn generate neutrons. A linear accelerator (Linac) creates protons at the ion source, accelerates them to an appropriate energy and steers them

A PID design method is presented. The work done is part of anattempt to find an automatic tuning algorithm for two times two systems inthe process industry. The method tries to minimize the impact of load disturbances. The method was mainly developed because previous designmethods with the same objectives could not handle the processesobtained in decoupled systems.

This paper describes an automatic tuning procedure for dead-time compensating controllers. A first order plus dead time model is identified from two step response experiments. The identification is based on the methods of moments. The model uncertainty is estimated automatically and used in the design to obtain a robust controller.

Measurement noise generates undesired control activity resulting in wear of actuators and reduced performance. The effects of measurement noise can be alleviated by filtering the measurement signal. New criteria based on the trade-offs between performance,robustness,and attenuation of measurement noise are proposed for assessment of the design. Simple rules for calculating the filter time constant

A performance comparison between PID and predictive PI (PPI) controllers, i.e., two different prediction methods, is presented. Optimization of controller and measurement filter parameters, considering load disturbance rejection, robustness and noise sensitivity, is performed for a batch of industrially representative processes. For a majority of the processes and the constraints chosen, results s

The ModeGraph library offers improved flexibility of hybrid modelling and incorporates powerful properties of the Mode-Automata semantics. Concepts from Finite State Machines (FSM), Sequential Function Charts (SFC)/Grafcet and Statecharts are efficiently utilised to provide a flexible modelling environment that a broad audience can feel familiar with. Being able to guarantee mutual exclusivity of
