Abstract :
Starting from a very general formulation of the Internal Model Principle it is shown that a robust controller tracking/rejecting signals generated by an exosystem can be decomposed into a servocompensator and a stabilizing controller. The servocompensator contains an internal model of the exosystem generating the reference and disturbance signals and the stabilizing controller stabilizes the infinite-dimensional closed-loop system.
