The invention discloses a control system of a servo drive electric cylinder. The control system comprises a host computer, a motion control module, a servo driver, an actuator, an electric cylinder and a data acquisition module, and is characterized in that an electronic cam module and a sine wave operation analytical model are arranged in the motion control module. The control system has the advantages that a set target operating frequency and a set amplitude parameter can be converted into the actual control parameters of the motor, namely the target position, the target speed and the targetacceleration, so as to achieve the control of the electric cylinder; the servo driver operates in an open-loop positioning mode; and the servo driver stops operating only when the electric cylinder has a large positional deviation, so that a long control response period can be achieved, thereby meeting the design requirements of the high-frequency sinusoidal trajectory movement and ensuring the continuity of the motion.
Description
technical field [0001] The invention relates to a control system of an electric cylinder, in particular to a control system of a servo-driven electric cylinder. Background technique [0002] Servo motors are widely used in the field of industrial control, and the open servo motion algorithm can meet some special and complex motion control requirements. The application in the elastic body test project requires the single axis of the servo electric cylinder to do a series of high-speed and high-frequency sine wave-like trajectory movements. The traditional control method is to use the traditional position mode, speed mode or torque mode, which can realize closed-loop control through its own or external signals to achieve precise target positions. When performing servo positioning control, the closed-loop algorithm inside the servo will calculate the required speed through the closed-loop position, and calculate the required acceleration through the closed-loop speed. The acce...
