Designing of control system for IIRI

Abstract

This thesis pioneers a groundbreaking approach to enhance motion and speed control in astronomical observations through the design and implementation of a novel system utilizing the Raspberry Pi 4B and Raspberry Pi Pico W. The proposed system aims to replace the existing control infrastructure of the IIT Indore Radio Interferometer, addressing its limitations and introducing a cutting-edge solution for precision radio astronomy. Leveraging the computational capabilities of the Raspberry Pi 4B, the system orchestrates the Raspberry Pi Pico W to generate PWM waves, finely regulating the motion of an AC servo motor. This innovative configuration enables unparalleled precision in telescope pointing accuracy and tracking capabilities. The integration of these components, a Raspberry Pi-based control system coupled with Raspberry Pi Pico for PWM signal generation, not only marks a significant departure from conventional approaches but also presents an unexplored avenue for achieving unprecedented levels of control in astronomical observations. The outcomes of this research promise to contribute to the advancement of radio astronomy instrumentation, setting the stage for a new era of precision and adaptability in the pursuit of unraveling the mysteries of the cosmos.
