DESIGN OF MONITORED CONTROL SYSTEM FOR CENTRAL AIRCONDITIONING SYSTEM
Building automation system (BAS) is an important part of intelligent building at present with the development of compture technology. The monitored control system of the central air-conditioning system in a TV building is designed which is one part of BAS. The monitored control system is constructed in the BAS of EBI (Enterprise Buildings Integrator) from an Automated Logic Corporation. The Composition and characteristics of this system are introdued. The hardware and software are presented. The software includes the EBI and CARE (Computer Aided Regulation Engineering) of the corresponding upper and lower controllers. At last the control strategy of the air-conditioning system in the building is discussed, which includes the PID control, fuzzy control and hybrid fuzzy-PID control algorithms. Especially the control method of temperature and humidity in the air-conditioning space is discussed. The experiments in a big studio of TV builidng show that hybrid fuzzy-PID control has better adaptability and stability, less overshoot, faster response and higher precision than PID control and fuzzy-control.
