For a good explantion google PID controller. The letters stand for proportional, integral, and derivitive. It's a feeback loop controller that "learns" over time.

Read wikipedia to get an overview of what it is.
P I D terms are values that define the motor behaviure in relation to the input control signal.
P proportional error : The output power is multiplied to this P konstant
I Integral error : The error accumulated over time, reduses steady state error.
D Derivative error, the D is the rate of change value.
