In this paper, we study the global robust output regulation problem for a class of multivariable nonlinear systems. The problem is first converted into a stabilization problem of an augmented system composed of the original plant and an internal model. The augmented system is a multi-input system containing both dynamic uncertainty and time-varying static uncertainty. By decomposing the multi-input control problem into several single-input control problems, we will solve the problem by solving several single-input control problems via a recursive approach utilizing the changing supply function technique. The theoretical result is applied to the speed tracking control and load torque disturbance rejection problem of a surface-mounted permanent magnet synchronous motor.
