Abstract

Notch filters are used in many industrial applications to attenuate undesired frequencies within signals. Such undesirable frequencies are common in flexible dynamic systems, power plants, medical monitoring systems, etc. In many aerospace flexible dynamic systems the desired center frequency shifts due to the nonlinearities and coupling of the system. The conventional approach in aerospace is to generate a large database filled with filter coefficients. This requires a significant verification and validation activity, as well as a large storage capacity for the filter coefficients. In this paper a model-based approach is used to design a notch filter system for a multivariable nonlinear system. Disturbance Accommodation Control ideas are presented and applied to notch filter design.
