Gain block problem?

If I want "k-" as a gain then what should I write in the gain configuration? Or what will be the gain configuration?

[Paul]

Are you referring to the Gain block in Simulink?

What is "k-" ?

[Rushi Patel]

Yes, I am referring the gain block in simulink. But I think I found the answer of the given question. "-k-" in the gain is represented as 30/pi. I wanted to convert speed into rad to rpm. Thank you for your support Paul.

Hi @Rushi Patel

If you have the Aerospace Blockset installed, then you can find and use this Angular Velocity Conversion block to convert unit of the input signal from rad/s to rpm.

https://www.mathworks.com/help/aeroblks/angularvelocityconversion.html

Double-click the block to set the Initial unit (rad/s) and the Final unit (rpm).

Else, you can also use the knowledge of "1 rad/s is equal to 9.5492968 rpm" to enter the value of 9.5492968 into the Gain block.
