2) A cascaded controller. Controller n°1 controls for example the power supplied to the heating resistor, or the surface temperature of that resistor using a close coupled temperature sensor. Controller n°2 controls the air temperature. Controller 1 is in the loop of the controller 2. Controller n°1 is fast, controller n°2 is slow. The system is always faster that way than with a single controller controlling everything. But requires hardware modifications, cost and complexity increase.

Can one cascade PID Controllers that drive SSRs?
