Speed feedback
PRACTICAL WORKS
• Study of the luminous barrier/frequency voltage converter.
• Study of the tachometric filter.
• Study of the loop amplifier and of the controlled switching power supply.
• Comparison of tachometric voltages and optical encoder + converter.
• Comparison of low rotation frequencies with and without feedback loop.
• Study of the feedback response for different values of loop gain.
This model is designed for the simplified study of a speed feedback on a closed loop, with a feedback signal generated either by a tachometric dynamo, or by an optical impulsion encoder. It consists of a direct current motor which drives a second direct current motor, functioning as a generator. The signal issuing from this generator is used as an image of the speed. The shaft assembly also drives a toothed disc, which cuts a luminous barrier, the impulses of which are applied to a frequency voltage converter. A direct current adjustable source integrated in the model is used as the voltage reference level. A switching supply controlled by the error voltage supply the motor.
