These are documents and circuits which will help learn Basic Temperature closed loop control, There are many ways to control temperature.
- ON-OFF Hysteresis or Dead Band Control.
- Proportional Control with Reset.
- Full PID Control, Manual and Auto Tune.
The first one is an electronic emulation of Thermostat or Electro-Mechanical Controls. The second is a Time-Proportional like a slow PWM. The third is the complete adaptive control.
While the first is like a limit switch, the second works like a SMPS, the third PID takes into account the speed of the process and dynamic changes or disturbances of the system and compensates in real time.
Example – In a Oven, one batch may have 100 metal boxes to heat, the second batch may have 10 boxes, the door may be frequently opened and the mains power (heater) may be fluctuating. A system that is able to adapt to these changes, without much readjustments is the objective of an ideal process control. The Accuracy and the Energy efficiency being the most important.
