This work deals with the application of extended inverse dynamic control to
a given constrained control problem. By choosing an extended inverse dynam
ic control the system is partially linearized leading to a representation o
f the system which consists of a double integrator system and a complementa
ry nonlinear system. This representation looks to be more suitable for the
solution of constrained control problems, rather than, the representation g
iven at the outset, This is demonstrated by solving an example concerning t
he constrained motion of an articulated crane. (C) 2000 Elsevier Science Lt
