摘　　要：针对无人动力伞(UPP)的飞行具有不确定性、非线性和复杂性的特点,建立了无人动力伞6自由度非线性动力学模型,仿真分析了模型对输入信号的响应特性.提出了无人动力伞在线子空间预测控制算法.该算法能及时地克服模型失配、时变及干扰等对飞行控制系统的影响,使有约束的预测控制能够在控制时域内保持最优.仿真结果表明,该算法能有效辨识仿真模型产生的输入输出数据,表现出了较好的跟踪性能和控制精度.According to the uncertainty, the nonlinearity and the complexity features of UPP （unmanned powered parafoil）, a 6-DOF nonlinear dynamic model for UPP is established. The response performance of UPP model to input signals is simulated and analyzed. A UPP online subspace prediction method is proposed which can overcome the effects of the uncertainty, the time-varying and the disturbance on the flight control system in time, and can keep constrained predictive control optimum in predictive horizon. Simulation results show that the method can identify the input and the output data generated by simulation model effectively, and it has excellent tracking performance and control precision.
