The paper considers the problem of achieving high quality control of the system with an object having a high-inertia component. Modeling a stabilization system with a classical proportional-integral-differential controller (PID controller) showed that when using such a controller, it is not possible to achieve the desired control quality due to the long time needed to establish a transition process with the required overshoot. We suggested a hypothesis that using a fractional order PID controller (FPID controller) it is possible to solve this problem. We carried out mathematical modeling of the system with the FPID controller and revealed that the FPID controller can significantly reduce the time needed to establish the transition process of the system under consideration. The study describes elements with fractal impedance based on a resistive-capacitive medium, and gives a description of their model. The adequacy of the mathematical model is confirmed by means of the sheet-oriented model in the LTSpice program using the selected model. Conclusions are made about the feasibility and necessity of conducting research in the field of design and manufacture of a FPID controller and elements with fractal impedance
