Modeling analysis and realization of mathematic model of all-parameter compensated in saturated steam flow

摘要

In this paper, an all-parameter compensated measure problem of saturated steam flaw is investigated, a sensitivity analysis of each operating parameter influence in flow measure is presented. The effect of these operating parameters to the accuracy of flow measure is analysed between given operating modes. On the basis, the method of system identification and parameter estimation is used to build mathematic model of all parameter compensated on- line measure in saturated steam flow, and the system software adopted with above model has been used to develop the multi - channel intelligent flowmeter.
