“…In the case of servomotors, feedback control systems provide a specified value for the position, speed, or any other output parameter of the motor. Based on [63][64][65][66][67], it is possible to identify the key aspects in the construction of this principle and draw conclusions about its advantages and disadvantages.…”

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.

“…In the process of industrial production, the controlled object with the characteristics of time delay is very common, and the time delay object is also difficult to control, especially the control of large time delay objects has always been a difficult problem the literature and the literature put forward the modelless adaptive control algorithm theory [1][2][3][4] , and proved the stability and convergence based on the full format modelless adaptive control algorithm [5][6] . The simulation and improvement of modelless adaptive algorithms are carried out in the literature and prove that modelless adaptive algorithms have effective control effects on large time delay systems, and the literature applies modelless adaptive control algorithms to the simulation of higher-order systems and nonlinear systems [7][8][9][10] , which proves that in high-order systems and nonlinear systems, modelless adaptive control algorithms also have good control and anti-interference effects [11][12] .…”

For large delay problems that exist in industrial process control we Put forward the Improved Model-free adaptive control algorithm. The advantage is that the model does not require the specific object ,the system can be controlled just by the output and input. In the improved algorithm by introducing a constraint entry of the rate of change of the output with large time-delay to reduce the impact of large delay on the system. Verify that the improved algorithm can control the delay system effectively by MATLAB and SMPT-1000 simulation in the system response speed and system stability.

Background: The electro-hydraulic load simulator is a semi-physical simulation system. It is used to simulate different loads on the bearing capacity object (steering gear system) under working conditions and further test the dynamic and static characteristics of the bearing capacity object. Therefore, it is widely used in important applications such as the simulation of various loads and the development of high-performance steering gear systems. Objective: By analyzing and discussing the electro-hydraulic load simulator equipment and its improvement methods, some useful conclusions have been drawn to predict the development of the electro-hydraulic load simulator and its key technologies. Methods: The current status of research on electro-hydraulic load simulator prototypes is discussed in depth. The electro-hydraulic load simulators are classified according to the loading system applying force (torque). The improvement methods of the electro-hydraulic load simulator, including the method of suppressing the extraneous force, the compensation method of nonlinear factors, and the method of establishing the mathematical model, are analyzed and summarized. Results: By summarizing the literature and patents on electro-hydraulic load simulation technology, the principle, and characteristics of different equipment and improvement methods are analyzed and compared, and future development of electro-hydraulic load simulation equipment and technology is discussed. Conclusion: The research on the characteristics of the prototype, the hardware means and control strategy to suppress the extraneous force, the compensation of nonlinear factors, and the methods of establishing the mathematical model are beneficial to improve the loading accuracy of the electrohydraulic load simulator.
