New Positioning Control of Stepper Motor using BP Neural Networks
نویسنده
چکیده
This paper presents a new approach based on the use of a knowledge base, in order to improve the angular resolution of the permanent magnet (PM) stepper actuator. The use of this technique is justified by the limits of the conventional technique when the static torque characteristic is high nonlinear. The conventional open loop microstepping technique which realised by a Pulse Width Modulation is described and discussed, in first part. In second part, a design of a new approach based on the use of back propagation neural network is proposed. The obtained simulation results confirm the efficiency of the new proposed approach.

متن کاملA New Technique for Controlling Hybrid Stepper Motor through Modified Pid Controller
Due to the development of digital control systems, hybrid stepper motors became more attractive to be used in robotics and computer numerical control machines where they have to perform high-precision positioning operations without any feedback sensor. However, at open loop control (especially at higher stepping rate), the speed response of the stepper motor suffer from large overshoot, oscilla...
