摘要：
We consider a single-input/single-output (SISO) nonlinear system which has a well-defined normal form with asymptotically stable zero dynamics, We allow the system's equation to depend on constant uncertain parameters and disturbance inputs which do not change the relative degree, Our goal is to design an output feedback controller which regulates the output to a constant reference, The integral of the regulation error is augmented to the system equation, and a robust output feedback controller is designed to bring the state of the closed-loop system to a positively invariant set, Once inside this set, the trajectories approach a unique equilibrium point at which the regulation error is zero, We give regional as well as semiglobal results.
