My real system (buck converter) can only take an input of 0 to 1 (duty ratio) from the PID controller output for the circuit due to it simulating reality (can't have negative or above 1 duty ratio in reality).
How can I constrain the PID controller output so that the genetic algorithm only looks at a controller output of 0 to 1 instead of -inf to inf?
You need to define upper and lower bounds. Are you using builtin command such as ga for genetic algorithm ? Is it code from steve brunton?
Hi Waheed Ur Rehman
I am not sure if the lower and upper bounds (of the ga command) would restrict the the PID controller output to 0 and 1. I think the upper and lower bounds would restrict the PID values rather than the PID controller output itself although I hope I am wrong.
I am using the builtin command for genetic algorithm yes. The code is from the steve brunton video linked yes.

Muhammad Abbas Khan that is my post on the mathworks forum. Thank you for the assistance nevertheless.
