Stepper motor performance can be compromised by noise and vibration, but an advanced high-torque micro-stepping algorithm can minimise the impact of both noise and vibration as well as increasing the resolution of the rotations. The embedded microcontroller which hosts the micro-stepper algorithm also provides additional flexibility to integrate current-limiting as well as adjusting the drive c...
Permanent Magnet (PM) stepper motors are widely used in precise systems which are affected by external disturbances, parameters uncertainty and saturated control. Also, an appropriate nonlinear controller is required when the problem is to track reference signal. This paper presents a robust adaptive controller to control rotor angular position in stepper motors. The main idea to make a robust ...
PURPOSE To demonstrate that high-resolution biometry is possible in mouse eyes in vivo, using real-time OCT with focal plane advancement by a stepper motor. METHODS OCT images of eyes were taken from nine 29-day-old C57BL/6 mice(18 eyes) on two consecutive days. A custom-built real-time OCT instrument with a stepper motor was used to advance the focal plane from the corneal apex to the retina...
In the mobile robot navigation, the ultrasonic sensors have been widely used for the obstacles detection and map building because of its cost and efficiency. Generally sensors are used to increase the accuracy of the obstacles position and decrease the time. In this paper an ultrasonic sensor is interfaced on to a stepper motor which will be constantly revolving and detecting the values of any ...
