What do you know about PID control?

PID uses the error to determine what value should be applied to the controlled device(plant) to make the input minus the feedback quantity equal to zero (indicating the controlled parameter is at the commanded input).

A PID controller uses the error (current error, rate of change of the error, and accumulated error) multiplied by some constant values($k_{p}$, $k_{d}$, & $k_{i}$) to determine the output parameter. In tuning a PID, one selects the $k_{p}$, $k_{d}$, & $k_{i}$ to accomplish the controller requirements.

i know how to build the controller with opamps using what capaitor and resistor value for setting up the time responses, but couldnt figure out this task algo...really bad at these types of algo, just couldnt figure out how dc motor has 150 degree position
