One such approach is called cascade control, which is routinely used in most modern computer control systems. Consider a chemical reactor, where reac tor temperature is to be controlled by coolant flow to the jacket of the reac tor (Fig. 8-34). The reac tor temperature can be influenced by changes in disturbance variables ...

WebThe variable to be manipulated, in order to have control over the process variable (PV), is called the MANIPULATED VARIABLE or MV. If we control a particular flow for instance, we manipulate a valve to control the flow. Here, the valve position is called the MANIPULATED VARIABLE and the measured flow becomes the PROCESS VARIABLE. WebIn a basic control system, a single manipulated variable is adjusted per the effect it …
