AB  - Purpose– The purpose of this paper is to present the results in the area of modern computer‐aided control system design tools relating to system identification.Design/methodology/approach– The finite‐frequency identification method was designed for the needs of active identification. The test signal represents the sum of harmonics with automatically tuned (self‐tuned) amplitudes and frequencies where the number of harmonics does not exceed the state space dimension of the plant. The self‐tuning of amplitudes is carried out to satisfy those requirements on the bounds of the input and output which hold true in the absence of a test signal.Findings– In this paper, the software implementation of finite‐frequency identification method in the system GAMMA is considered. GAMMA is the two‐level computer‐aided design (CAD) tool for identification and controllers algorithms synthesis for linear plants.Practical implications– The system GAMMA is the complete and really working system.Originality/value– A new structure of the CAD tool for engineers‐developers of control systems is proposed and its program implementation is described. The new variant of finite‐frequency identification method with self‐tuning of identification parameters (test signal and identification time) is considered.
