We consider a single-input single-output nonlinear system which has a well-de"ned normal form with asymptotically stable zero dynamics. We study the design of a robust output feedback controller that incorporates a linear servo compensator to achieve asymptotic tracking and disturbance rejection. We

β¦ Synopsis
A fundamental limitation exists in the achievable transient performance which is possible to be obtained in the tracking and disturbance rejection of a non-minimum phase system, and this limitation can be characterized completely by the number and locations of the right-half plane zeros.
