GPC control design for a temperature and humidity prototype using ICD analysis

In this paper the design of a multivariable control system for an air conditioning process is presented. The controller design is based on the classical generalized predictive control (GPC) scheme, while the resulting stability, robustness and performance properties are analysed in the context of individual channel design (ICD). The design specifications in this work are those established by the Mexican Government Metrology Office (Centro Nacional de Metrologia, Mexico); it indicates that the temperature and humidity values must be kept within certain ranges. The designed control system has been tested using the Gunt Hamburg ET605 recirculating air conditioning trainer. Real time results are included in order to show the excellent performance of the control design
