Linear quadratic optimal control for an experimental OHS aircraft

This paper describes the computer simulation and experimentation of a remotely controlled model aircraft under linear quadratic control. The aircraft is first modelled mathematically using Newton´s laws and coordinate transformations which form a set of nonlinear differential equations. The mathematical model is linearized and used as the basis for the linear quadratic problem. The control system is simulated and then implemented on the remotely controlled aircraft. The aircraft performance greatly improved with the addition of model based linear quadratic control
