Abstract

The individual channel design framework advanced by J. O´Reilly and W.E. Leithead (Int. J. Control., vol.54, pp 1-46, 1991) is justified for all multivariable system structures (RHP poles and zeros). In particular, it is shown that individual channel design on the original 2-input 2-output cross-coupled multivariable system is valid irrespective of the degree of cross-coupling. Second, the influence of (individual transfer function, channel, transmission) RHP zeros on controller design and closed-loop channel performance is elucidated. Third, a new result concerning the existence of fixed stabilizing controllers for uncertain systems is presented
