How to set initial conditions in simulink

WebSep 27, 2024 · Probably the IC block will fit your needs. The IC block sets the initial condition of the signal at its input port, for example, the value of the signal at the simulation start time (t_start). The block does this by outputting the specified initial condition when you start the simulation, regardless of the actual value of the input signal. WebMay 23, 2008 · First, rewrite the equations as a system of first order derivatives. Second, add integrators to your model, and label their inputs and outputs. Third, connect the terms of the equations to form the system. Example: Mass-Spring-Damper The mass-spring-damper system provides a nice example to illustrate these three steps.
