Abstract

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.

Keywords

Micro-stepping, PWM, Solar tracking and Xilinx ISE
