By integrating the building structure as thermal energy storage into the building services concept, thermally activated building systems (TABS) have proven to be economically viable for the heating and cooling of buildings. Having already developed a

Thermoaktive Bauteilsysteme (TABS) haben eine zunehmende Bedeutung bei der energieeffizienten Kuhlung und Heizung von Gebauden, doch ihre Regelung/Steuerung fuhrt in der Praxis oft zu Problemen. Mit dem Ziel, diese Probleme in den Griff zu bekommen,

SUMMARY A research project on the control and design of thermally activated building systems (TABS) has been started in May 2004. This paper presents one selected result after three years of work: A comprehensive TABS zone control strategy with a mod

Different forms of discrete time controllers with integral action, control signal saturation and antiwindup feedback (i.e. Plaw, PlawD, Plaw-P cascade, I-aw with observer based feedback) are investigated. It is shown that high gain antiwindup is not

A qualitative approach for detecting faults or sub-optimal operation in a class of heating, ventilation and air-conditioning systems is presented. In particular, qualitative models are used to describe the steady-state operation of a controlled centr

The feasibility of a qualitative approach for detecting faults in an air-conditioning system is considered. The system considered is a multi-zone variable air volume air-handling unit, and the faults investigated include types which result in deterio

In this paper a fuzzy anti windup scheme for an observer for the reference value of the flow temperature of a heating installation is designed. The observer consists of an averager in series with a characteristic curve. A nominal design of the time c

The problem of estimating the parameters of a quasiperiodic signal consisting of a sum of a given number of sinusoidal signals with known frequencies but unknown time-varying amplitudes and phases superimposed by some additive noise sources is treate

In this paper anti windup schemes for PID controllers are proposed that consider not only actuator constraints but also process state constraints. The schemes are fuzzy generalizations and combinations of the traditional conditional integration anti
