Optimizing Pole-assignment Region of Flight Control System for the Large-type Passenger Plane
On the base of analysising the large-type passenger planes characteristics, combining with flight quality requirements for manned aircraft, this article cornered the flight quality requirements into the regional limits for closed-loop pole assignment,then optimized the region to three kinds of region which is easy to express in LMI, for example, trapezoid, sector and disc, this make it convenient to design the flight controller. In the end, the article assigned the closed-loop poles of a flight controller into a discand combined with those no pole assignment constraints.The simulation results showed that the flight controller with pole assignment constraints had good steady performances, dynamic performance and robustness. The defect was that the optimization caused some conservatism.
