Robust discrete adaptive control for a class of multivariable systems

This paper presents a simple discrete adaptive control procedure that maintains global stability and robustness with respect to boundedness in the presence of any bounded input or output disturbances. The order of the plant and the pole-excess may be large and unkown, while the order of the controller may be very low. The present algorithm is restricted to the class of systems that can be stabilized via some known output feedback configuration, yet it may provide a simple adaptive control solution to most practical problems that appear in the control literature and it may be especially effective in large-scale systems.
