The workshop on Control Mechanics, originated in 1988, beca-me an annual event and gained considerable recognition inadvancing control of nonlinear and uncertain mechanical sy-tems and promoting application of advanced mechanics in con-trol. The fourth meeting continues the tradition with 17papers containing original and recent work of the partici-pants developed in 3 basic directions: feed-back control ofuncertain systems, flexible mechanical structures and flightcontrol.
