| Results: |
Application of LPV techniques to the design of the longitudinal axis of the NASA
High Speed Civil Transport (HSCT). The difficulty is that the HSCT is an extremely
flexible aircraft which will require the active attenuation of flexible body modes as well
as a standard flight controller. The LPV control designs will be compared with the
current Boeing flight controller and augmented structural mode control system. The
LPV designs will be tested in pilot-in-the-loop simulation at NASA Langley and NASA
Dryden. |
| Application: |
The robust, gain-scheduled multivariable controllers perform as well as the
current designs. These results lend support to these techniques to design current and
future flight control systems. As systems become more highly coupled, robust, gain-scheduled multivariable techniques offer a major benefit over classical methods in terms
of achievable performance, robustness and overall safety. |
