Environmental temperature measurement and control in coal mine movable refuge chamber is a very important issue of environmental control system in refuge chamber. This paper proposes a method to reconstruct the system's mathematical model by using extended Kalman filter, and adopts Robust adaptive control method to study the control algorithm of environment in the refuge chamber. Based on the theory analyses, hardware platform of the system has been constructed by using Advanced RISC Machines (ARM) single chip microcomputer as control device, and the software of the system has been compiled. Experiment on simulating model and practical testing results have proved that the designed system of this paper can control the temperature in refuge chamber effectively. And the system has strong robustness and good response speed.
