Abstract

Electronic control systems offer a big potential for improved environmental control inpig buildings. Their use is however limited to those types of controllers that can replicate the features of older electromechanical controls. Current research and development work, which is not confined to pig building applications, is largely concerned with extending the use of microprocessor-based controllers to incorporate features such as: (a) control based on parameters other than simply air temperature; (b) control based on algorithmswhich predict the pigs’ needs; and (c) control which integrates alarm, fail safe and monitoring.

To accommodate these features more advanced controllers are used, however their use in practice is likely to be limited by a number of technical, economic and ergonomie constraints.
