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…
Servo motors are typically employed in closed-loop position control; for example let us consider the following application, where the angular…
ZigBee is an open wireless standard for low-rate networks. It is an IEEE standard 802.15.4 protocol. The physical layer radio…
This is a controller with only 2 switching states, that is, the output signal is switched ON and OFF depending…
Modbus is an open standardized communication protocol that was founded by Modicon. Initially it was designed for the communication among…
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…
A microprocessor by itself is not a computer. To be functional, the microprocessor must be connected to other ICs that…
