Lost step detection on a stepper motor
This project was carried out at Overview Ltd., a London company which specialises in high precision video-surveillance equipment. Overview produces devices that include a camera driven by two stepper motors, and an image-processing unit. Magnetic encoders are used to detect external disturbances and failures. Overview is willing to develop an algorithm capable of detecting lost steps, and in the longer term, capable of giving precise position related information without using encoders.
