| Results: |
Application of LPV techniques to the design of power-approach lateral-directional
flight control law for the F-14. These control designs were compared with the newly
developed digital flight control system (DFCS) which will be introduced into the fleet in
the coming years. In piloted simulations of the powered-approach landing, lead test pilot
Lt. Scott Kelly and Lt. Poindexter of the DFCS ights, gave the LPV gain-scheduled
designs a Cooper-Harper rating of 4. We have redesigned these LPV controllers and are
waiting for an opportunity to test them in pilot-in-the-loop simulation. |
| Application: |
The high performance, robust, gain-scheduled multivariable controllers per-
form 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. LPV software
will soon be available in commercial software (specifically the mu-Analysis and Synthe-sis Toolbox) provide industry and government labs usable advance control analysis and
design tools. |
