Based on instrumental variable method,presents a new method,to compute the heat transfer coefficient of wall surface.

A new experimental procedure is proposed based on instrumental variable method for analyzing wall surface heat transfer process and deducing wall surface heat transfer coefficient.

Besides,according to the numerous and complex influencing factors of discharging states,instrumental variable method is used to further handle the biased autoregression model.

Modification of biased target parameter estimation for static single bearings-only observer by instrumental variables;

For General model system of existing correlated interferential noise,this paper researches on a new method of identification,first of all system model is approximated by using to FIR model,and to obtain a Box-Jenkins model which can be identified by the Instrumental Variable method,and finally to determine the parameters of the original systems by means of the model equivalence principle.

This article puts forward the experimental methods to analyze the heat exchange process of outside surface of walls of construction by instrumental variable technique and derive the heat exchange coefficient of outside surface of the wall body.
