摘　　要：以XV-15为原型,建立倾转旋翼飞行器纵垂通道三自由度非线性全量模型并线性化。针对其定翼机模态下的纵垂向控制问题,采用级联控制方案,设计基于状态空间模型预测算法的控制器,不同短舱角采用同一组参数,实现无切换控制。仿真结果表明,所设计的飞行控制系统性能好、鲁棒性强,能够满足应用要求。With XV-15 being a prototype,a three-degree freedom nonlinear model was established and linearized.To solve the problem of longitudinal and vertical control of the tilt-rotor in fixed-wing aircraft mode,a controller based on state-space model predictive control strategy was designed by using cascaded control scheme.The same group of parameters was adopted for different nacelle angles to realize non-switching control.The simulation results show that the designed flight control system conducts excellent performance,has strong robustness,and is able to meet application requirements.
