Expert Solution

PID controllers can be tuned automatically or manually. Most of PID controllers nowadays use auto tune function and learns and reacts to process. They calculates PID settings and activates output. They select the optimal PID setting. These settings can be fine tuned manually as well.
A person can fine tune the PID manually by having enough info on the process being controled. The optimal values must be calculated for gain, reset time and rate for PID controller. The reset time must be set to max and rate to 0. Then the gain is to be increased until loop oscillates at constant amplitude. Then gain is set to half and the reset time is adjusted . Then finally the overshoot must be minimized by increasing the rate of PID loop.
Advantages are:

They can be used to manage many processes at a time
Provides appropriate gain control
Provides auto tune
works very fast and efficiently

PID controllers consist of Proportional, Integral, and Derivative blocks that manipulate the error of the Process Variable signal depending on their own characteristics. Some controllers use these three blocks while some other controllers use the P block or the P block in conjunction with another one. In any case, the P block seems to be always present. Discuss if we can have controllers that employ only an I block or a D block alone. Describe why or why not using...
