RateLimiter

Limit rate of change of signal

Library

Blocks/Nonlinear

Description

This block limits the rate of change of an input signal u (left) and passes it as output signal y (right):

RateLimiter_equation1

This limitation is implemented using a first-order delay filter to approximate the rate of change (du/dt). The dynamics of this approximation is governed by parameter T (time constant).

The start value of the output is defined by parameter y_start.

Parameters

    RateLimiter_0

  • sMax [-] : Maximum slope (sMax): Scalar.
  • sMin [-] : Minimum slope (sMin): Scalar.
  • T [s] : Time constant (> 0) (T): Scalar.
  • y_start [-] : Start value of output (y_start): Scalar.

Ports

  • Port 1 at left position: implicit input fixedport numbered 1.
  • Port 1 at right position: implicit output fixedport numbered 1.
