ABSTRACT:
A motor monitoring and control circuit calculates a value parameter for a position of the motor at given instants. The same parameter (which may be position or speed of a rotor) is then measured at subsequent instants. These values are used to compute a future value of the parameter. The motor monitoring and control circuit is advantageous in that it can be used for any type of motor and can be easily and quickly fitted to a motor without the need for expensive and time consuming initial measurements and computations of characteristic properties of the motor in order to calibrate it. Similarly, automatic compensation is made during operation.
