Kinematic Planning And Control Of Flight Simulator

Flight Simulator is important aviation simulation equipment, which is used to train pilots. To provide the true feeling of flight, it needs to simulate all kinds of complicated motion state. Compared to the real aircraft, the flight simulator is controllable, non-destructive, economic and other advantages in flight test.This paper takes the six degrees of freedom as a campaign platform Stewart institutions, and adopts the hydraulic-driven approach. By controlling the length of the six hydraulic cylinders on the platform to change the position and attitude, and providing six degrees of freedom instantaneous overload, Flight Simulator can simulate aircraft pitching, trundle, drift, fluctuation, longitudinal and lateral migration.In this paper, parallel robot inverse method, consider the impact of Stewart workspace, using inverse kinematics compiled MATLAB program to calculate the six basic movement Stewart under changes in the length of each bar. And through the application of Pro / ENGINEER finish the simulation of software movement, through institutions kinematics and dynamic analysis, using the concept of coupling strength, analysis of the coupling characteristics of institutions. In the end, Using PID control strategy for single-channel valve-cylinder system, the control experiments.The study conducted by Stewart, has been on the kinematics, dynamics, trajectory planning, and coupling analysis and control strategy for some of the conclusions of the flight simulator studies have a certain reference value.
