“…NNC is a control method that uses neural networks and principles of artificial intelligence to approximate nonlinear control functions and the mathematical model of the process. This type of servo motor control is used in systems where it is impossible or difficult to create an accurate mathematical model, such as multi-level autonomous control systems [109,110]. This method resonates with fuzzy logic-based control methods and possesses similar positive qualities such as flexibility, adaptability of control, and the ability to react quickly to external influences [111].…”

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.

To ensure the stability of vertical mold casting machine casting, and improve the quality of casting, for which the electro-hydraulic servo system of the traditional active disturbance rejection control(ADRC) of the nonlinear function is not smooth and the parameters are difficult to adjust as well as the dual hydraulic cylinders synchronization of the problem of low precision, a new type of nonlinear function is used. To improve the effect of parameter optimization and tuning, the snake optimization algorithm(SO) is used to optimize and tune the parameters of the nonlinear state feedback rate and the expansion state observer, which is more convenient for parameter tuning, and also makes it possible to reduce the error. The simulation results show that compared with the PID controller and the traditional ADRC controller, the ADRC controller based on the Ifal function and SO has a certain jitter suppression effect as well as good tracking and synchronization performance, which can effectively improve the tracking and synchronization accuracy of the twin cylinders of the electro-hydraulic servo system.
