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.

Description

technical field [0001] The invention relates to a speed synchronous control technology, in particular to a speed synchronous control method and system of a load simulator. Background technique [0002] Electro-hydraulic load simulator (EHLS) is a key device for hardware-in-the-loop simulation of aircraft servo mechanism. It is used to simulate the aerodynamic load on the steering gear during flight. Its performance directly affects the confidence of the evaluation of the servo mechanism of the flight control system. The difficulty of its control is to realize accurate force loading during any motion of the position control system, so the load simulator is a typical electro-hydraulic servo system with strong motion coupling. [0003] Relevant scholars at home and abroad have carried out extensive research on how to suppress the adverse effects of motion disturbances. The methods are roughly divided into three categories, one is the structural compensation method. It starts w...
