“…Considering that asynchronous motors are more powerful, this type of servomotor is produced only for alternating current. Synchronous motors have lower power but provide greater accuracy; in conjunction with direct current, they allow for achieving smaller motor dimensions and using this type of servomotor for autonomous mechanisms [31][32][33][34][35].…”

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.

“…Unlike brush motors, brushless models have a wider range of rotation speeds, allowing them to be used in processes requiring high-speed movement. However, controlling a brushless motor requires the presence of a PLC, regardless of the tasks it performs [33,[36][37][38].…”

“…One of the biggest weaknesses of conventional brushed DC motors is their maintenance. Because of the friction caused by brushes, classic DC motors require the periodic exchange of certain components [7,8]. Comparing both constructions, it is unquestionable that the brushless DC (BLDC) motor has a simplified internal structure.…”

This paper deals with the application of a fuzzy-logic-based controller for a drive with a BLDC motor. Two main aspects of the work are presented in this paper. The first of them is focused on the design process of the fuzzy model. For this purpose, the rules of the applied fuzzy system are defined according to the Lyapunov function. The gain coefficients of the controller are optimized using the Chameleon Swarm Algorithm. Various issues and aspects were analyzed in the simulation tests (robustness against parameter changes, the influence of the controller parameters on the precision of control, stages of optimization, etc.). The presented work confirms the assumptions regarding precision and stable operation (also in the presence of changes in the object parameters—the mechanical time constants of the engine) in connection with the applied fuzzy speed controller. Moreover, the second part of the manuscript presents the low-cost power electronic device developed for laboratory tests. It uses STM32 ARM-based microcontrollers (state variable measurement, control algorithm calculation, control signal generation) and a Raspberry Pi 4B microcomputer (control application—reference value and parameter definition). The experiment performed for the control structure—an electric drive with a BLDC motor—verified the theoretical considerations.
