Discrete Varying Lowpass
Discrete Butterworth filter with varying coefficients
Libraries:
Control System Toolbox /
Linear Parameter Varying
Description
The block implements the Tustin discretization of a continuous-time Nth-order Butterworth filter. The result is a digital filter with unit DC gain and varying cutoff frequency.
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, see Model Gain-Scheduled Control Systems in Simulink.
