摘要：

The design and flight-testing of a multivariable helicopter flight-control system is reported on. The design was based on H-infinity optimization and a low-order rigid-body model of the aircraft dynamics. The test-aircraft was a modified Bell 205. Evaluations were carried out at hover and low/moderate speed. The controller successfully engaged first time and provided adequate-to-desired (level 2) performance on a number of tasks. This is believed to be the first successful Right-test of an H-infinity optimal multivariable controller on a rotorcraft. A summary of data gathered during over eight hours of test-flights, together with some handling qualities evaluation, is presented.
