The process of finding these values is referred to as tuning. If you want a pid controller without external dependencies that just works, this is for you.
But there is auto tuning software that exists, and there are quadcopter. The operator can achieve the fastest response time and smallest overshoot by following these instructions carefully. The information for tuning this three mode controller may be different from other controller tuning procedures. Then only using proportional control, the k p value should be increased gradually from 0 until the system shows sustained oscillations and this value of the proportional control is known as critical value k cr. This white paper from omega engineering discusses how to tune a pid controller. Choosing a controller gain is accomplished easily with pid tuning software. At the completion of a program, the controller can hold the set point, stop the outputs, or loop to one of the 30segment programs.
