| Summary: | 碩士 === 逢甲大學 === 自動控制工程所 === 98 === The purpose of this research is to accomplish the aerodynamic force and control technology development of VTOL(Vertical Take-off and Landing) and automatic transition for the tilt-rotor aircraft. We have built the mathematic model and control executive system of the hybrid rotary/fixed wing vehicle.
Firstly, we simulate and validate the aerodynamic force and control law with Matlab, and then build a real-time executive system for the flight simulator. Using the executive system, we can simulate and validate the related mathematic model, control law, flight dynamic behavior of VTOL and automatic transition.
In this research, we sample 20 points in the maneuver to obtain 20 sets of state condition. For each state condition, we can get a set of Jacobian matrix of linear dynamic equation by using numerical linearization. And then we design the control system by using pole placement and zero phase error tracking control (ZPETC) methods to achieve the required performance. Besides, we also design the VTOL flight control system with the back-propagation neural network and demonstrate the flight dynamic behavior. Finally, we have constructed flight simulation monitor using VC++ MFC 3D/VR technique on Windows. In this way, we can monitor and validate the actual behavior with virtual reality.
