摘要
Abstract
Horizontal takeoff and landing vehicles with integrated aero engines,blended wing bodies,and combined cycle power have the potential to be swiftly deployed and utilized in repeated aerospace round-trip missions with great transportation efficiency.However,their flight dynamics are affected by strong nonlinearity,aero-engine-elastic coupling,longitudinal-lateral kinematic coupling,and flight attitude-trajectory coupling,making control design challenging.In this regard,a flight dynamics model is established in this paper,which describes various coupling characteristics of a general blended-wing-body combined-cycle-power vehicle.Then,its flight dynamic characteristics are analyzed.By combining traditional PID control with dynamic inversion to suppress couplings,a multi-loop control law that is simple to apply is created.The multiple stochastic simulation results show that the control law not only helps suppress couplings but also achieves good tracking performance in attitude and trajectory,as well as good control robustness and anti-interference ability under uncertainties such as modeling,environment,and sensing.关键词
