Tips: What is PID control in temperature controller?
In temperature controller, PID control is setting parameter P to non-zero (set parameter P to zero is called ON/OFF control). PID controller adjusts the heater to change the measurement value (PV), and the deviation value (EV=SV-PV) is obtained by compared with the set value (SV). Deviation value (EV) is fed back to the PID controller through the sensor and PID controller can obtain the heater opening of the next adjustment through calculation. PID control system belongs to closed-loop control and the heating equipment can work at different power. At all time periods, the actual value and the set value are infinitely close. In theory, it can realize error-free control between the actual temperature and the set temperature.
PID control is suitable for occasion that has high requirement on temperature control accuracy, such as incubator and wine making technology.
