无人倾转旋翼机飞行动力学建模及操纵技术

The Fight Dynamic Model and Control Strategy for Unmanned Tilt-rotor

针对无人倾转旋翼机的飞行特点和操纵方式,建立了一套适合于倾转旋翼机飞行操纵特性分析的飞行动力学模型,研究无人倾转旋翼机全包线飞行操纵与控制策略。在Simulink仿真环境中分别建立直升机模式、飞机模式以及过渡飞行模式仿真模型,通过配平计算,得到各飞行模态工作点处的配平操纵量,为分析无人倾转旋翼机的全包线飞行策略和操纵输入提供研究基础。

According to flight characteristics and control feature,the flight dynamic model of the unmanned tilt-rotor was built,which was utilized for researching the operator and control strategy for the full flight envelop.The helicopter,fix-wing and transition flight model were developed in the Simulink situation,the equilibrium points for the different flight stage were obtained by trimming the nonlinear flight dynamic model,which were provided the basis for analyzing the full flight model control input for unmanned tilt-rotor.
