culties with position control. Elastic link vibrations with inherent nonminimum phase response coupled with large rotations create a complex nonlinear dynamic system for control. The ability of the flexible robot to follow a prescribe trajectory is an important issue. In case of more complex operati

acecraft is considered to be a rigid body whose attitude can be described by two sets of equations, namely, the kinematics equation, which relates the time derivatives of the orientation angles to the an- gular velocity vector and the dynamics equation, which describes the time evolution of the angu
