Analysis of a tape transport motor control system

The modeling and analysis of a motor control circuit of a tape transport system will be performed in this project. Particular attention will be given to the technique used to generate the reference ramp to bring the system up to speed. This ramp generator uses a saturation type non-linearity to achieve a fast rise time with no overshoot or settling time. Also, the use of an optical encoder with a Butterworth Filter, as a frequency to analog converter, will be investigated as a means of determining the motor output speed. This can then be used as the negative feedback signal for the motor control system.
