摘要：
An unknown disturbance estimation method for non-minimum phase systems using a parallel feedforward model has been proposed. The parallel feedforward model is adopted in order to improve the estimation performance and it must ensure minimum phase property of the augmented system consisting of the plant and the parallel feedforward model. In addition, the frequency response of the parallel feedforward model must match to that of the plant. This paper derives design conditions of the parallel feedforward model as LMI conditions and designs the parallel feedforward model by solving a convex optimization problem.
