| Abstract: | The working principle of a new type of no pulsation continuous rotary electro hydraulic servomotor applied to simulator is introduced.The Lugre frication model used in this paper can meet the requirements for friction compensation of hydraulic system, because it could describe complex friction behavior, and two step off line identification methodology of the Lugre parameters has been proposed.By way of experiment research,we have got a new type of friction model of continuous rotary motor,and the low speed and step response of the motor have been researched.Experimental results have proved that using fraction compensation could eliminate stick slip motion at the low speed and this servomotor could be applied to simulator. |
