MIMO controller design for decoupling aircraft lateral dynamics

The principal lateral motion of an aircraft is described by a minimum of fourth order coupled state variable model. It is interesting to investigate how a decoupling controller can be designed. The Youla-parametrization is a simple method to design controllers. The KB-parametrization is a successful extension of this method for two-degree-of-freedom (2DOF) systems. The paper extends this methodology for multivariable case and applies to the decoupling lateral control.
