The use of software by automation engineers to adjust regulators is an important task.
The aim of the study is to develop software for the tasks of optimal adjustment of PI controllers.
In the article, based on the analysis of the functionality of modern software products for tuning automatic control systems, the main requirements for the development of software for tuning of automatic controllers have been stated. The interface of the developed PI-Tuner software product for determination of optimum values of coefficients of proportional and integral terms of the PI-controllers has been presented. The description of functionality of the software product has been shown. Among functional features of the software are: the analysis of control process for plants of the first, second and third orders with and without delay; building of plots, which describe of the control; calculation of qualitative indicators of control in the time domain; determination of the optimal coefficients of the PI-controller on the basis of the metaheuristic method of optimization with taking into account several control indicators (overshoot, settling time, etc.).
The main directions of further development of the software product have been indicated. Among them are: expansion of its functionality in terms of calculations of a wide class of plants, improvement of the interface, possibility of application of known in engineering practice methods of controllers tuning, etc.
Key words: software, automatic control, PI-controller, tuning
