Summary:In this paper we study the problem of converting a tracking
controller to a manoeuvre regulation controller for a nonlinear
nonminimum phase control system. First, a tracking controller,
consisting of feedforward and static state feedback, is designed to
guarantee uniform asymptotic trajectory tracking. The feedforward is
determined by solving a stable noncausal inversion problem. Constant
feedback gains are determined based on LQR optimization and assumed
satisfaction of a robustness inequality. A manoeuvre regulation
controller is obtained from the tracking controller by introducing a
suitable state projection that is related to the LQR feedback gains.
Properties of the closed loop, including local asymptotic convergence of
the transverse errors, are developed
