Abstract

Extraneous force is the main factor impacting the precision and dynamic characteristic of the electro-hydraulic load simulator. The structure and mathematical model of simulator is analyzed . then the improved compensation method based on the structure invariable principle is proposed to eliminate the extraneous force. The method use the velocity signal of the rudder servo system as the feed-forward compensation signal .and the speed signal is reproduced by integrating the given position signal of the rudder servo system. Then use the least square procedure for on-line identification to get tuning phase of the compensation signal. The experimental result show that improved compensation method is efficient obviously.
