Tyler Veness f0e3bb5164 artf4165: D term of PID controller now uses change in input instead of change in error ...

This avoids large additions introduced by the D term when a step change occurs in the setpoint. Otherwise, the changes return the same values. Let error = setpoint - input and prevError = prevSetpoint - prevInput. If the D term is calculated via error - prevError, then:

error - prevError = (setpoint - input) - (prevSetpoint - prevInput)

If we ignore the setpoint changing, then we get:

error - prevError = (setpoint - input) - (setpoint - prevInput)
                  = prevInput - input
