Nonlinear Longitudinal Control of a Supermaneuverable Aircraft

This paper describes a technique which can be used for design of feedback controllers for high performance aircraft operating in flight conditions in which nonlinearities significantly affect performance. Designs are performed on a math model of the longitudinal dynamics of a hypothetical aircraft similar to proposed supermaneuverable flight test vehicles. Nonlinear controller designs are performed using truncated solutions of the Hamilton-Jacobi-Bellman equation. Preliminary results show that the method yields promising results.
