Methods of correction of dynamic characteristics of measuring instruments in the mode of their usage

It is known that the determination of the dynamic characteristics of mechanical quantities sensors is performed on the response to the known effects. First, the error description of the model is estimated, then the parameters of the mathematical model for the order chosen by the differential criteria are found. The need for such criteria is caused by using the error description of the model. It should be taken into account that in case of increase of the order of the model its description error decreases, i. e. the higher the order of the calculated mathematical model, the more accurate description of the response. However, in case of deliberate overstatement of the order described by the model, the probability of occurrence of non-existent components and/or splitting of one of them, becomes rather high. Hence the problem arises, the essence of which is to develop a technique of modeling the known response, characterized by the least errors. It is noted that the task set is complemented with restriction: for its solution it is necessary to find for the required calculated mathematical model such parameters, which satisfy the minimum error. Numerical simulations verify how well the developed technique will determine these parameters, which cannot be achieved in the processing of real data. The solution of the above difficulties is seen in simulation modeling in the correction tasks of dynamic characteristics of measuring instruments without interrupting their work. Here the main problem is that neither order of the mathematical model nor its error is known. To select the mathematical model it is necessary to minimize the error of describing it, taking into consideration the total effect of all the components. The proposed method helps determine a combination of the properties of an object, which are characterized with features and values of the parameters at a certain time period, or to specify its characteristics without deinstallation of the object.
