A gain scheduled multivariable design for a manual flight control system

A full envelope multivariable flight control system is developed for the Variable Stability In-Flight Simulator Test Aircraft (VISTA). Separate control laws are designed for the longitudinal and lateral directional axes. Output feedback controllers with integral error states are created using linear quadratic synthesis and simple linear transformations. Linear point designs are integrated into a gain schedule to create a full-envelope nonlinear control system.<
