| Research Abstract |
Two types of adaptive control law were studied with the aim of improving the reliability of manned space transportation. One is a novel nonparametric approach and the other is a conventional parametric approach. On the basis of the first approach, a flight control system was designed by combining disturbance observers and a feedback linearization technique. A numerically simulated automatic landing on a runway was successfully carried out using the data of a space shuttle orbiter. In the second method, lateral directional motion was adapted to design a minimum phase system, and its effectiveness was confirmed by numerical simulation with a disturbance observer. A fault-tolerant control law was also developed so that a flight performance can be maintained, even if one or two actuators among the five control surfaces break down.
