| Abstract: | In order to eliminate value and improve precision and performance of electric-hydraulic servo system,the improvement scheme based on the structure invariance principle is proposed on the foundation of mathematical modeling of Sinusoidal force mechanism.The method is proposed with the use of position feedback signal of the driving servo system to identify,the structure of speed compensation signal to proceed flow feed-forward to compensate and restrain redundant force.In order to compensate the redundant force effectively,it uses least square procedure for on-line identification to compensate signal and correct phase.This method can provide the theoretical basis and guidance for the compensation of redundant force of Sinusoidal force mechanism. |
