| The theme of the thesis roots in a high-technology project which was charged with Navigation College. The aim is empoldering an aeroengine characteristics simulated system. According to testing the aeroengine characteristics, researching the aeroengine going at the different aviation state . The state of the spout is very important to the aeroengine going. Thus, how to control the going of the spout with reason is very important.The spout executed machine designed in the thesis, is used to adjust the going of the aeroengine according to the different flight state. In the thesis, adopting the symmetry electro-hydraulic servo-valve in synchronization control of asymmetrical hydraulic cylinder to execute the servo tracking of the spout executed machine. After get the DEEC signal from the digital electronic controller , electro-hydraulic servo-valve transform the DEEC signal to the hydraulic pressure signal in order to control the working of the executed machine. At last, location sensor feed back the displacement to the digital electronic controller to complete the servo tracking of the spout executed machine.Based on the mathematic model of the spout executed machine , adopting the traditional PID control and the Fuzzy control method to research the going state of the system. Simulating and controlling with MATLAB/SIMULINK, comparing the different of the two control methods in dynamic characteristics and static characteristics. |
