Abstract

The invention relates to a speed synchronous control method and system for a load simulator. The speed synchronous control system for the load simulator comprises a loading system, an inertia load and a tested position servo system; the inertia load is used for simulating the rotary inertia of the tested position servo system in actual work; the loading system is used for simulating the borne force or torque of the position servo system in actual work, and loading the force or the torque to the tested position servo system through inertia loading. After the adoption of the speed synchronous control method and system for the load simulator, the requirements of a structural invariance method based on velocity feedback signals, on high quality speed and acceleration signals, can be effectively avoided, and the problem of poor interference eliminating capability under large and middle load in the traditional speed synchronization method can be effectively solved.

[0145] As an implementation manner, step S10 may include:

[0146] The servo valve 11 of the position servo system 10 controls the position hydraulic motor 12 to output a force or torque signal according to a control command.

[0147] Step S20 may include:

[0148] S21: The loading servo valve 31 of the loading system 30 controls the loading hydraulic motor 32 of the loading system 30 according to the current signal of the servo valve 11 of the measured position servo system, so that the force or moment output by the loading hydraulic motor 32 is applied to the loaded hydraulic motor 32 via the inertial load 20 Measure position servo system 10.

[0149] As a preferred solution, step S20 may also include:

[0150] S211: The loading servo valve 31 controls the loading hydraulic motor 32 according to the pressure difference signal between the two chambers of the position system, so that the force or moment signal output by the loading hydraulic motor 32 is applied to the measured position servo system 10 via the inertial load 20.

[0151] Among them, the pressure difference signal between the two chambers of the position system is the pressure difference between the two chambers of the actuator of the position servo system.

[0152] As a preferred solution, step S20 may also include:

[0153] S212: The loading servo valve also controls the loading hydraulic motor according to the torque signal output by the loading hydraulic motor, so that the force or torque signal output by the loading hydraulic motor is applied to the measured position servo system 10 via the inertial load 20.
