how to make my waveform in control and design simulation run continuously?

Another option is to use dBohls suggestion and keep the Final Time equals to "inf", change the solver to Fixed Step Size like "Runge-Kutta 1 (Euler)", check "Synchronize Loop to Timing Source" and check "Auto Period" under "Timing Parameters". This will allow you to slow down the simulation.

Then you also have to change the signal generator from "step" to a "Pulse Signal" and adjust the frequency to give enough time for the system to get to steady-state. This would allow you run indefinetily and you can see the parameters change happening while you are running. This would mimic the response you would have by trying to tune a plant online.

Thanks Barp, i had try out the second method after found that it is work, thankyou very much 🙂
