IC (Simulink Reference)

Set the initial value of a signal

Library

Signal Attributes

Description

The IC block sets the value of the signal at its output port at t=0.

The IC block is also useful for providing an initial guess for the algebraic state variables in the loop. For more information, see Algebraic "Loops in Using Simulink.

Data Type Support

An IC block accepts and outputs a signal of type double.

Dialog Box

Initial value: Specify the initial value for the input signal.

Examples

These blocks illustrate how the IC block initializes a signal labeled "test signal."

At t = 0, the signal value is 3. Afterwards, the signal value is 6.
