Integrate design of the control of a flight simulator motion system


A flight simulator is a virtual reality tool that gives the pilot an impression that he/she flies an actual aircraft. The simulator normally consists of several subsystems, among them, the motion system. The motion system provides inertial cues to stimulate the sensation of self-motion as it would occur in the aircraft. However, the driving mechanism have a significantly smaller range of motion compared to the real aircraft, therefore, it is impossible to exactly reproduce the aircraft motion cues in a simulator. The motion drive algorithm is used to reproduce the motion cues realistically as possible without hitting the physical limits of the simulator. In this context, the present project aim to development a control strategy of a flight simulator motion system driving by a 6 DOF paralle-robot-type mechanism where the controller design will treats the motion drive algorithm and the motion mechanism control as a single problem.First, relevant mathematical models of the parallel robot and motion perception are developed, which will be used to design and evaluate the controller. Then, the structures and control strategies are selected by considering the mechanism dynamics and workspace, flight simulator motion system performance requirements and perception models.After that, controller synthesis will carry out. Finally, methods to evaluate the controller's performance are defined in order to choose the structure and control strategy, that should be used in a flight simulator motion system. (AU)
