PID

PID-controller in additive description form

Library

Blocks/Continuous

Description

This blocks defines the transfer function between the input u and the output y as a textbook PID controller:

PID_equation1

For a more practically useful PID controller, use block LimPID.

Parameters

    PID_0

  • k [-] : Gain (k): Scalar.
  • Ti [s] : Time Constant of Integrator (>0) (Ti): Scalar.
  • Td [s] : Time Constant of Derivative block (>=0) (Td): Scalar.
  • Nd [-] : The higher Nd, the more ideal the derivative block (>0) (Nd): Scalar.

Ports

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