Ramp rate %/min limiter in simulink

How to add ramp rate limiter to implement 5%/min output?

Below is my model but it lacks the running 5%/min . I want to limit output to 5%/minute of the running Kw input signal.

Thanks

Feed constant value of 0.05 to "up" and -0.05 to "lo". If you want to prevent a value from increasing more than 5% per minute, the actual rate for that is: 0.05/60.

You could use the static rate limiter for this.

thanks, but i checked the rate limiter blocks it executes per time step .

I have a time step Ts=0.1

so im thinking to use 0.05/60/0.1. Is this the correct slew rate?

Time step has been taken into consideration. It should be 0.05/60. Take a look at the Help document. Make an experiment.
