Flight control laws are designed for the X-29 forward swept wing demonstrator aircraft using a design technique based on multivariable control law theory developed professor Brian Porter. The computer-aided design program called MULTI is used to develop and refine the control laws. MULTI also simulates the complete closed-loop control system and generated appropriate time response plots for analysis. Aircraft dynamics for several points in the flight envelope are represented by linearized state space equations obtained from NASA Dryden, and agency responsible for the development and testing of the X-29. Decoupled longitudinal and lateral equations are used to design separate longitudinal and lateral controllers. Control laws are developed to stabilize the aircraft and perform longitudinal maneuvers (direct climb, vertical translation, and beta pointing) at three different flight conditions, with and without first order-actuator dynamics and computational time delay added to the simulation. The responses are compared.
