Title : Pulse Width Modulated Fpga Based Digital Controller For Microstepping Stepper Motor Drive For Solar-Array Drive In Satellites

Author Name : Sachin Angadi, Satyanarayana Kumari B , H .V. Saikumar 

Synopsis :

This paper discusses FPGA based digital controller designed for solar tracking in satellites. The proposed controller can replace the conventional full-step controller for stepper motor in all positioning applications owing to its increased resolution capability and reduced effect of mid-frequency resonance. The concept of microstepping is discussed using PWM. The design is implemented in Xilinx ISE. Results are presented to show the substantial advantages of the proposed methodology.
