碩士 === 國立交通大學 === 電機與控制工程系 === 91 === A salient VR dynamic simulation system can provide the user a feeling of realistic interaction. Thus, to deal with the high cost and danger problems in flight tests, we may use the VR-based flight simulator, to replace the training using real planes. PIO (Pilot-Induced Oscillation) is an infamous unstable phenomenon resulting in flight accidents. PIO is primarily due to the pilot’s improper manipulation that causes the saturation of the actuator, leading to phase lags and unexpected oscillations. In this thesis, we first introduce the VR flight scenes and discuss the establishment of a flight dynamic model. We also describe the force-reflection joystick developed in our laboratory. We then discuss those causes leading to PIOs, and methods proposed to detect PIOs through these years. Based on these discussions, we develop a fuzzy PIO detector for the VR flight simulator, and let it integrate with the technique of phase compensation to alleviate the PIO phenomena. The simulation results demonstrate the effectiveness of the proposed fuzzy PIO detector and also the phase compensation module.
