A ride comfort control system is designed for a STOL aircraft with the aim of reducing lateral acceleration levels within the passenger compartment. The control laws are designed using both state feedback and gust feedforward loops based upon a rigid aircraft model. The feedback gains are found using linear optimal control theory. The gust feedforward gains are determined from a generalized inverse formulation that minimizes gust excitation of the dutch roll mode. The lateral directional control surfaces available are the existing rudder and ailerons. Control law performance is evaluated using root-mean-square values calculated from the spectral response of the aircraft with a Von Karman gust spectrum input. The turbulent gust input is based upon Etkin's four-point model which includes linear gust spatial gradients.
