Pulsbreddsmodulering av styrsignal till DC-motor
The purpose of this work was to investigate if the choice of frequency, on a pulse width modulated control signal to a DC motor, might influence the behaviour of the system, as wall as to see how the system reacts in connection with the controlling by means of such a signal. I came to the conclusion that the frequency was not critical seen from the system's point of view, but should be chosen
