Problems solved by technology

The designed state feedback controller can ensure that all signals are bounded, and the tracking error converges to a small neighborhood of the origin, but its controller design does not deal with system disturbances, and when the mode is switched, the instantaneous The state response may have a sudden change, consume more energy, and may damage the system actuator
[0008] However, the active disturbance rejection motion control method in the related art does not consider the complex multi-modal characteristics of the system with practical engineering significance, and it is difficult to suppress the sudden change of the transient response of the actuator, that is, the sudden change of the control command when the mode switches. The stability of the closed-loop system is reduced, and the control accuracy of the system is reduced.

Abstract

The invention relates to a multi-mode robust active disturbance rejection motion control method and system. The method includes the following steps executed in sequence: judging the current control mode of the controlled system according to the controlled system information; wherein the controlled system information includes the status information of the controlled system; according to the controlled system Determine the ideal control command corresponding to the current control mode of the controlled system; determine the actual control mode of the controlled system according to the information of the controlled system and the ideal control command Control instruction. The control method and system of the present invention can realize that the control method can realize the correction of the ideal control instruction to obtain the actual control instruction, suppress the transient response of the system when switching between different modal control laws, realize the control of the multi-modal system, and improve the It improves the control accuracy and the stability of the controlled system, so that the multi-mode controlled system has strong robustness.

Description

technical field [0001] The present invention relates to the technical field of motion control, in particular to a multi-mode robust active disturbance rejection motion control method and system. Background technique [0002] Motion control technology is widely used in today's industries, such as motor motion control, CNC machine tools, robot control, etc. Motion control refers to the control of motion quantities such as position / displacement, speed, and acceleration. Compared with other types of motion actuators, electric motors are used as motion actuators, which have the advantages of simple structure, fast response, high precision and efficiency, and are conducive to realizing high-performance motion control such as high-speed or low-speed, high-precision, etc., in modern industry, civil, It has broad application prospects in fields such as medical treatment, transportation and military affairs. [0003] Due to the influence of factors such as friction, system parameter...
