      Robust switching adaptive control of multi-input nonlinear systems 

      Kosmatopoulos, Elias B.; Ioannou, Petros A. (1998)
      During the last decade a considerable progress has been made in the design of stabilizing controllers for nonlinear systems with known and unknown constant parameters. New design tools such as adaptive feedback linearization, ...
