AI Technical Summary

Problems solved by technology

Generally, the hydraulic servo system has low damping, and the load simulator is no exception. Generally, it does not exceed 0.3. Using traditional control methods often causes overshoot, which affects the rapidity of the system and reduces the loading accuracy. Therefore, increasing the hydraulic damping ratio improves the system. is very important; and the motor loading system is often due to friction and other factors, the damping is too large or too small, resulting in system response that cannot meet the requirements

Abstract

The present disclosure provides a motion dynamic loading method, comprising the following steps: (1) estimating the system damping of the loading system; (2) controlling the system damping according to the estimated value of the system damping in step (1). The motion dynamic loading method of the present disclosure performs closed-loop control on the damping of the loading system, so that the loading system can maintain the optimal damping state at all times.

Description

technical field [0001] The disclosure belongs to the field of servo control, and specifically relates to a motion dynamic loading method that can realize closed-loop torque control / position control in a servo system while optimizing the system damping ratio, which can improve the loading accuracy and rapidity of the loading system, and improve system performance. Background technique [0002] The servo system, also known as the servo system, is a feedback control system used to accurately follow or reproduce a certain force or position control. The servo system is an automatic control system that enables the output controlled quantities such as the position, orientation, and state of an object to follow any change in the input target (or given value). [0003] The loading equipment is the main high-precision test equipment for detecting and evaluating the performance of the navigation and guidance system. It is a typical servo system. The aerodynamic moment load spectrum si...
