This monograph demonstrates how the performance of various well-known
adaptive controllers can be improved significantly using the dual
effect. The modifications to incorporate dual control are realized
separately and independently of the main adaptive controller without
complicating the algorithms. A new bicriterial approach for dual control
is developed and applied to various types of popular linear and
nonlinear adaptive controllers. Practical applications of the designed
controllers to several real-time problems are presented. This monograph
is the first book providing a complete exposition on the dual control
problem from the inception in the early 1960s to the present state of
the art aiming at students and researchers in adaptive control as well
as design engineers in industry.
