A lateral stability augmentation and attitude pilot system for a Boeing-707 transport model is analyzed and designed with eigenstructure assignment method. The concepts and principles of eigenstructure assignment methods are first summarized. The extended aircraft lateral dynamics, including actuator dynamics and a washout filter on the yaw rate, is modeled as a multivariable time-invariant state equation, with seven state variables, two control inputs, and four measurement outputs. The desired (respective) eigenstructure are selected according to the requirements on the transient performances and on the decoupling dynamics between roll and yaw maneuvering. Both the full output and the constrained output feedback strategies are used in the closed-loop system design. Digital simulation results are illustrated.
