Varying Notch Filter
Notch filter with varying coefficients

Description
The block implements a continuous-time notch filter with varying coefficients. The instantaneous transfer function of the filter is given by:
wheregmin,damp, andfreqare the values supplied at the corresponding input ports. These parameters control the notch depth and frequency as shown in the following illustration. The damping ratiodampcontrols the notch widthΔ; largerdampmeans largerΔ.
Use this block and the other blocks in the Linear Parameter Varying library to implement common control elements with variable parameters or coefficients. For more information, seeModel Gain-Scheduled Control Systems in Simulink.
