Disturbance decoupling for a class of nonlinear MIMO systems by static measurement feedback. (English) Zbl 0974.93038

Summary: The disturbance decoupling problem for a square-invertible nonlinear system is stated and solved by static feedback of measured variables only, in contrast with standard solutions which assume that the full state is available for feedback. The results are valid for left-invertible systems as well.
