In order to control the flight attitude for an aircraft,a ground semi-physical flight attitude simulation system was established based on a dSPACE system.The invariant set principle and Passivity-based Controller (PBC) design method was used to deal with the aircraft simulation system,for it was a kind of higher order nonlinear control system with strong coupling.A nonlinear Euler-Lagrange (EL) dynamic model with controller constraints for the aircraft simulation system was established by the Largange method.Then,based on the internal characters of EL systems and the recent results on invariant set stability theorems of nonlinear impulsive hybrid systems,a saturation dynamical hybrid controller for the aircraft simulation system was presented,and the mathematic simulation was also given out to verify the effect of the proposed controller.Finally,a semi-physical simulation experiment was undertaken with the proposed controller.Obtained results show that the dynamic response time is about 20 s,steady-state accuracy is less than 5% and the overshoot is about 25%.These data indicate that the designed saturation controller is valid and robust to both the system parameter errors and disturbance.
