Abstract
Environmental temperature measurement is a very important issue of environmental control system in coal mine movable refuge chamber. This paper proposes a kind of dynamic compensation method for the temperature sensors by using extended Kalman filtering algorithm, which is based on the reference model. The more precise compensator has been got, by using extended Kalman filter for dynamic compensation of the parameter identification. Therefore, offset errors on the temperature sensors are automatically compensated. Experiments on simulating model have proved that the method of this paper can acquire satisfied compensation results. And, the method can be used on the temperature measuring system in the coal mine movable refuge chamber.
