We deal with model uncertainties as expressed in the presence of an unknown vector w
– depending upon the state x = (x1, x2)T – in the system description:
dx1 ⁄dt = p1(x) + B1(x)u + G1(x)w,
dx2 ⁄dt = p2(x) + B2(x)w.
Only available information: Bounds for w, wx, initial value (at t = 0) for w and x, measured output y = x2 for all t ≥ 0.
We present for this scenario a new approach to standard control problems based on a proposal for on-line-prediction of w(x) along the actual trajectory. The tools are non-conventional: The control law is a mixture of closed and open loop, depending upon time-varying parameters which are produced by a nonlinear observer.
