EnergyPlus runtime actuation questions

edit

Hi. I'm trying to implement some papers that control a few parameters during runtime. I'm using Gym-Eplus to vary the values but I'm not sure if the following can actually be controlled.

• Can we control the frequency of a VFD during runtime using an actuator? (In Hertz)

• Is the Return Air Outlet’s Setpoint Temperature similar to what is observed as Return Air Temperature Setpoint in BMS systems?

• Can we vary the Fresh Air Damper’s opening percentage in a chiller system during runtime using an actuator?

• Can we vary the chilled water valve opening percentage to an AHU system during runtime using an actuator?

I couldn't find any relevant actuators in the .edd file created. Thanks in advance.
