Hardware Implementation of Aircraft Landing Controller by Evolutionary Computation and DSP

Abstract

This paper presents a hybrid control scheme for the aircraft automatic landing system. PID control law is adopted in the controller design. Disturbance adaptive capability is demonstrated through hardware in the loop simulations. The control scheme uses PID controller with evolutionary computation technique. Control gains are selected by real-valued genetic algorithms. Different crossover methods are utilized to improve the performance of conventional automatic landing system. Hardware implementation of this intelligent controller is performed by a DSP with VisSim platform. The proposed intelligent controllers can successfully expand the controllable environment in severe wind shear conditions.
