Abstract : An approach to adaptive flight control is described which uses outputs from a relatively simple parameter tracking computer to adjust flight control system parameters. A unique characteristic of the parameter tracking mechanism is the ability to function with almost any type of disturbance as an input, including normal pilot activity, wind turbulence, and oscillations due to control loop instability. This may be accomplished without special test inputs or limit cycles. (Author)
