环境温度测量是煤矿移动避难硐室环境控制系统的一个非常重要的问题。提出一种基于参考模型的扩展卡尔曼滤波算法对温度传感器进行动态补偿的方法。利用扩展卡尔曼滤波器对参数辨识进行动态补偿，得到了更为精确的补偿器。因此，温度传感器上的偏移误差会自动得到补偿。仿真模型实验证明，本文方法能够获得满意的补偿结果。并且，该方法可用于煤矿移动避难硐室内的测温系统。
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.
