The mode of control is the way in which a control system makes corrections relative to an error that exists…
PID Controllers can be applied successfully to most control problems in process control, electrical drive systems and servo mechanisms due…
In a number of process control problems, we may have more measurements (controlled variables) than manipulated variables. Hence, it is…
We have a number of control theories that have been put forward on how to design control laws to accomplish…
In a process plant, we typically have a number of control goals that require different algorithms and types of information…
This is a controller with only 2 switching states, that is, the output signal is switched ON and OFF depending…
Analog signals pass continuously through a full range of values for example a measuring device converts the process variable (PV),…
Consider the following figure illustrating a position control system employing a microprocessor-based controller with parallel ports: Figure 1.0 Microprocessor-based controller…
An analog controller typically employs op-amps to provide the necessary gain and signal processing. Let’s consider the flow control system…
Typically a control system should be designed to work together with an already existing process. The control design problem can…
