Hi Everyone

I have a question regarding to Simulink.

Is there a way to switch between two transfer function block based on the simulation time.

For example, when t <= 100, input signal will flow into the first transfer function, when t > 100, input signal will flow into the other transfer function block.

Please advise me.

Thank you for your help.

Tommy

Not exactly,

the clock block outputs the current running time when you simulate a model. (0, 0.01, 0.02,... if you simulate in fixed-step with a sample time of 0.01 s.)

the '10' in the editor is the final time of the simulation.

if you want to change the time parameters of the simulation, make some changes in the configuration of the model.

Simulation->Configuration parameters (or ctrl+E).
