摘要

This paper describes two topics about failure accommodation of large transport aircraft, especially for control surface jam, which can be caused by hydraulic system faiolure: first, controlling the aircraft with complete loss of hydraulic pressure using engine throust only; second, taking advantage of slow effectors such as stabilizers and engines to counteract the disturbances caused by the stuck surfaces. Commands to the slow effectors are given by steady-state inputs of the proportional-plus-integral type optimal regulator. To illustrate the effectiveness of the proposed methods, computer simulation is conducted using linear models of the B-747.
