How can I get Genetic algorithm produced PID values to work in simulink model?

I have ran the Genetic algorithm code with an ITAE cost function at time step 1e-06. The gapidbook matlab m file presents the Ga command itself along with defining parameters such as population...

How to eliminate Steady state error from Reinforcement learning genetic algorithm code?

The following code (see 1st 2 images attached) is used to produce PID controller values that are designed to control the system (G). The code finds the PID controller values (noted as k) by using...

How to constrain genetic algorithm input u?

My real system (buck converter) can only take an input of 0 to 1 (duty ratio) and I need to constrain the system so the controller action keeps within this bounds. How can I do this? The code for...

How can I limit the PID controller output to a constraint of 0 to 1 for genetic algorithm?

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...
