Abstract

A motor control system for a closure mechanism, the system comprising: a first buffering circuit adapted to buffer a first waveform from a motor adapted to receive an electrical supply; a simulation circuit adapted to take the electrical supply and to simulate an effect of the motor on the electrical supply and to output a second waveform; a second buffering circuit adapted to buffer the second waveform; and comparison means for comparing said first and second waveforms.
