Abstract
The paper proposes a plan to effectively restrict the surplus force incurred by position disturbance of the steering engine during the dynamic loading of electro-hydraulic servo load simulators through improving the traditional structure invariance principle.Fourier transform is used to determine the frequency component in position signal of the steering engine,and least square method is used to rectify and sum phases of speed signals of steering engines corresponding to each frequency component,from which the systematic and accurate speed output signals of the position of steering engines can be obtained.The signal can be used for flow compensation of the loading system to eliminate the surplus force of the system.Simulation result reveals that the improved scheme can more effectively relieve the surplus force of load simulators.关键词
