In this article, a new approach is proposed for the problem of output voltage reference trajectory tracking in a boost converter with unknown, piecewise constant, load resistance values, under the restriction of noisy output voltage measurements alone. We use a nonlinear algebraic parameter estimation approach for the fast computation of the actual value of the stepwise changing load.With this information, a reduced order nonlinear observer for the inductor current is updated as well as a static passive output feedback control law derived on the basis of the exact tracking error dynamics and Lyapunov stability considerations. The average nonlinear adaptive observer-controller scheme is implemented on the switch regulated converter using the averaging features of a Σ − Δ modulator.
