Based on Kalman Filtering Theory Gas Forecast System Research

Based on modern control theory´s method, the research and the exploration gush out the process modelling using the Kalman filtering principle to the damp to carry on the real-time forecast. Carries on the description to the gas discharge process is the discrete system, uses the state space model, uses the preceding time the estimated value and the present time observed value renews to the state variable estimate, realizes to the gas denoising most superior estimate and the predict that is also suitable for the computer observation system´s use. Has confirmed the algorithm feasibility through the experiment simulation and the sea day coal factory measured data contrast, for the gas forecast that has provided a new mentality.
