Enumerate three valid methods to discretize a continuous con
Solution
Continuos control system: A control system is a device, or set of devices that manages, commands, directs or regulates the behaviour of devices or systems.
The control system compares the output of plant to control the signal and applies the difference as an error signal.
Today, most such systems are constructed with programmable logic control (plc).
The notation of ladder logic is still in use as a programming idiom for PLCs.
2. On-Off control-
A thermostat is a negative feedback controller, when the temperature (the process variable or PV) goes below a set point( SP) ,the pump is powered .
Simple on-off system like these are cheap and effective .
3. Linear control- It uses linear negative feedback to produce a control signal methamatically based on ther variables, with a view to maintain the controlled process within an acceptable operating range.
