ABSTRACT: In this paper, a suboptimal controller for the longitudinal attitude of an aircraft is presented.
Linear quadratic form control method is used to design a LQR controller for the system to improve its longitude
short-period dynamic performance. Genetic algorithm is applied to select two weighting matrixes, and the
optimal selection is obtained ...
