Practical Design of Flight Control Systems: Some Problems and their Solutions

Abstract

The flight control system design, though quite satisfactory on paper, many times gives surprises during the actual flight. This is due to unanticipated behaviour of the vehicle structure
or the aerodynamic characteristics, or the higher-order dynamics and nonlinearities, etc. The paper describes few such cases in which problems were faced and their solutions found, and
which gave satisfactory performance subsequently
