A better understanding of closed-loop control, and how to tune it, can be found by looking at the individual parts of the PID equation and the effect of each on the controlled output By Bill Dehner ...

For example, traditional step motor systems run in open loop control. That means the drive electronics continuously supply current to the motor whether or not the load is demanding torque.
