Abstract : An engineering design and realization of redundant digital servo system for direct drive valve (DDV)
actuator is presented. The DDV servo actuator is a new generation of elect ro2hydraulic redundant actuator ,
which has been used in many advanced aircraft . The redundant digital servo system int roduced in this paper
has been applied in an advanced t raining plane , and accomplished it s preliminary flight test s. The redundancy
level of servo system for DDV actuator and it s design concept are described. A simulation model oriented
st ructure parameter of DDV actuator is built , and so does the discrete model of redundant digital servo system.
A simulation is carried out to analyze the performances of DDV actuator , including static and dynamic charac2
teristics , sample f requency , and characteristics of monitor. In order to verify the performance of DDV actua2
tor , the redundant digital servo system is tested in a new way —rapid prototyping based on real2time SIMU2
L IN K/ xPC simulation , the result s show that the performance of the presented system is satisfied.
