Question

Cascade control is achieved by using two controllers to manipulate________

A. Two separate controllers
B. One final control element
C. Set Points
D. One process variable
E. Two separate transmitters

Answer 1

Cascade control involves two controllers working in hierarchy to manage one final control element in order to maintain the desired process variable at the setpoint.

The Correct option is; D. One process variable.

Step-by-step explanation:

Cascade control is a control system strategy that utilizes two controllers where the output of one controller is used as the setpoint for another. In cascade control, two controllers work in a hierarchical manner. The primary controller adjusts the setpoint of the secondary controller to achieve the desired process variable.

In this strategy, there is only One final control element that the secondary controller manipulates to maintain the process variable at its setpoint. The primary controller's goal is to manage the setpoint of the secondary controller so that disturbances are dealt with swiftly and the overall process performs optimally.

Cascade control is achieved by using two controllers to manipulate one process variable. In cascade control, there are two controllers: the primary controller and the secondary controller. The primary controller adjusts the setpoint for the secondary controller, which then adjusts the final control element.
