**4. Discussion**

From the presented results, it is obvious that the proposed electronic constant twist angle control system meets the requirements for its function, namely that it can achieve, sufficiently accurately and quickly, the desired constant twist angle of the pneumatic tuner of torsional oscillations. It is possible to assume that the proposed system will increase the technical level of the equipment where it will be applied.

However, it is well known that every technical solution has advantages and disadvantages. The use of the presented electronic constant twist angle control system provides the following general advantages:


In our further research, we are planning to verify the proper tuning of a torsional oscillating mechanical system with fan load characteristics using our electronic constant twist angle control system.
