To study the dynamics of a control object, it is necessary to obtain its transfer function or construct a model of it. The process of identification was carried out by Simoyu’s method and by means of the program Ident, which is built into the system Matlab. The input and output variables of the object were observed by performing an active experiment. A stepped control action was applied and a recording was made of the resulting output data, which was in the form of a transient response. To eliminate experimental errors, the tabulated data was smoothed with the use of a cubic spline after normalization. Double smoothing was performed with a step of 0.04 sec and then a step of 0.02 sec to record the volume of data.
