I need the following
PID loop to provide a defined motor speed for the following.
1 x motor speed controller operating from 0-5V (one way only).
Feedback from a tacho [1 digital pulse per revolution].
Ground Speed Sensor: [ pulse count (Digital –Point version or derivative) / sample interval] x [meters/pulse]
PID needs to operate for motor RPM from 1 to 100 rpm.
Motor speed controlled by: [ground_speed from ground speed sensor] x [gspeed_gain].
code to operate a Stellaris LM3S ARM processor
This shouldn't provide any difficulty. I got both LabVIEW for ARM and an EK-LM3S8962 available for use; plus the fact that I used those for developing an Advance Control project previously should allow for a fast, efficient and professional finish for your task.
