How does a controller apply control to a secondary process?
That controller in turn uses the actuator to apply its control effort directly to the secondary process. The secondary process then generates a secondary process variable that serves as the control effort for the primary process.
How is the output of a primary controller used in a cascade?
The output of the primary controller is used to adjust the set point r2 of a secondary controller, which generates a control signal to the controlled process. The process output y1 is fed back to the primary controller, and a signal from an intermediate stage of the process y2 is fed back to the secondary controller.
Who is responsible for the change control program?

Can a case inside another case in a switch case in C?
Case 0 -> Close the window where I am now and after this there is no chance of executing other cases. As Second Window is the Window containing 4 Quadrants. Case (1-4) -> All are executable but can be executed one at a time. There can be another switch statement inside a cases (nested switch case statements).
