Microwave heating interface - How to simulate power that changes over time

Hello. I'm simulating microwave heating equipment with microwave heating and heat transfer in solids interface.
My microwave heating equipment has PID controller so it controls its port power to reach target temperature.Input power of the microwave heating equipment varies from 0% to 100% over time.
How can I change the input power of port that changes over time in Microwave heating module?
I appreciate any advice.

In a frequency-transient study the RF power can be an explicit function of time.
You can easily implement a proportional or proportional-derivative controller by defining an integration or average coupling variable. A PID controller is also possible but may require ODE physics.
