Abstract
Model based control strategies are not well established in the heating ventilating and air conditioning industry yet. However, these techniques offer considerable advantages over traditional approaches based on expert knowledge and therefore may overcome deficiencies of existing control concepts. This paper outlines a model based control policy for an industrial test plant. The method uses describing functions to avoid undesired limit cycles. The proposed technique proves to be a systematic tool to improve the performance of heating ventilating and air conditioning systems.

In order to achieve the desired tracking performance, a prefilter V (s) is also included. However, it has no impact on the limit cycle analysis and is therefore omitted.
