In our previous article Digital PID Controllers, we discussed some basics of PID controller implementation as software algorithm on aputer. In that article, we simplify the matter by omitting the effect of sampling period on the PID parameters.

A PID controller is an integral part of the temperature control system of an industry. It is typically used to control the temperature of the premises. Here, the input of the PID controller is obtained from a temperature sensor and the output is fed to a fan or a heater. The fan or the heater; therefore, acts as a control element.

A typical problem encountered when using integral feedback is excessive “wind-up” causing the system to wildly overshoot the setpoint. This can be alleviated in a number of ways - the WPILib PIDController class enforces an integrator range limiter to help teams ovee this issue.. By default, the total output contribution from the integral gain is limited to be between -1.0 and 1.0.

Applications. Thude the following. The best PID controller application is temperature control where the controller uses an input of a temperature sensor & its output can be allied to a control element like a fan or heater. Generally, this controller is simply one element in a temperature control system.
