Abstract

Many methods have been proposed for unknown disturbance estimation problems. Several methods can be applied to non-minimum phase systems, but it is difficult to improve unknown disturbance estimation performances because of the phase lags of the systems. A method using a parallel feedforward model that enables good estimation performance for non-minimum phase systems has been proposed. In this paper, the effectiveness of the method is verified through numerical simulations and experiments.
