controlled variable x unintentionally.

In all cases, the regulator attempts to

readjust the controlled variable x to

therol (cascade

control)ble w and the controlled variable

x by using the final control element.

This process runs continuously so

changes in the reference variable are

always detected. However, a system

deviation will also occur if the reference

variable is constant but the

controlled variable changes. This happens

when the flow through the valve

changes in response to a switching

operation, a cylinder movement or a

change in load. The disturbance variable

z will also cause a system deviation.

An example of this is when the

pressure drops in the air supply. The

disturbance variable z acts on the
