MATLAB: How to give Initial Condition to Transfer Function

Question

Hello All,

I want the graph to start at 5 after it leaves the transfer function block in Simulink.

However, it starts at zero as default.

I have tried to use the Transfer Fcn with initial inputs but did not succeed -the output osciallates between 5 and -5.

Any help is appreciated. Thanks.

Answer 1

From the doc:

Specifying Initial Conditions

Initial conditions are preset to zero. To specify initial conditions, convert to state-space form using tf2ss and use the State-Space block. The tf2ss utility provides the A, B, C, and D matrices for the system. For more information, type help tf2ss or see the Control System Toolbox™ documentation.

HTH.
