In general, controllers are used to change chamber and/or element inputs while the
solver is running. You can use them in Steady and Transient analysis. Use
controllers to gauge a variable(s), apply a calculation (for example, a transfer
function), and then manipulate a variable(s).
Flow Simulator has three types of controllers.
Feed-forward Controller (create using “Controller” from the Element
Library)
Mission Controller (create using “Controller” from the Element Library)
PID Controller (create using “PID Controller” from the Element Library)
