查询词典 flight control

This paper studies optimal helicopter flight operations in the event one-engine failure. A three-dimensional point mass with a yawing motion of UH-60A has been used to study RTO and CTO from an elevated heliport or from a heliport, A first order dynamic of the OEI contingency power is considered. Flight after engine failure are formulated as nonlinear optimal control problems.

Then, aerodynamic parameters in different flight conditions are used to imitate the uncertainty of the system, and the digital simulation of closed-loop system designed is performed. The results show that the system can accomplish asymptotic decoupling of roll angle, sideslip angle and head-on angle for aircraft, and the system is provided with the function for restraining uncertainty in the system. This illustrates that the flight control system designed has not only good decoupling characteristic, but also better robustness.
