Modeling and Analysis of Servo Control of Aeroengine Actuator Cylinder

WU Ji-lin;ZHANG Jin;JIN Lin-shan;LI Ming-lei;AECC Aero Engine Control System Institute;  
In view of the application and theoretical analysis of the structure of a typical aeroengine valve-controlled asymmetrical actuator cylinder under load condition,the influence of the forward and reverse loads of the actuator cylinder on servo actuation control was discussed. A method for modeling and analyzing servo control system of valve-controlled asymmetrical actuator cylinder was presented. The analysis results of this method in the project case were compared with the actual project test data. The results show that the method is practical and reliable,and the confidence of the model is high. It has guiding significance for practical application. At the same time,in order to make the control effect of actuator cylinder round trip consistent,the direction of load should be designed as reverse load,and the load force should be designed in the vicinity of FL0.
