“…The main technical characteristics of servomotors are as follows [18,[52][53][54][55][56][57]: Motors with the function of maintaining a constant rotational speed are also used in laboratory setups of a digital twin of a wind generator [49], as well as in diagnosing damage to bearings [50,51] depicted in Figure 3a,b. Motor control is carried out using a frequency converter, allowing the selection of an appropriate motor control mode, adjustment of controller settings for different operating conditions, calibration of control to eliminate malfunctions, and more.…”

“…The main technical characteristics of servomotors are as follows [18,[52][53][54][55][56][57]: For example, in bearing fault diagnosis setup, discrete motor control is used to maintain a constant rotational speed. The use of a potentiometer to set an analog speed signal is not appropriate because there is a high probability of additional disturbances that would affect the rotational speed of the output shaft.…”

Servomotors have found widespread application in many areas, such as manufacturing, robotics, automation, and others. Thus, the control of servomotors is divided into various principles and methods, leading to a high diversity of control systems. This article provides an overview of types of servomotors and their basic principles and control methods. Principles such as digital signal processing, feedback control principle, field-oriented control, and integration with Industry 4.0 are discussed. Based on these control principles, the article presents popular control methods: PWM control, current control, two-loop control, fuzzy-logic control, and programmable control. The article concludes with a comparison of the presented methods on several criteria, and as an example, it includes the results of modeling a servomotor using the fuzzy-logic control method.
