Modelling and Simulation of Elevation Position Control of a Giant Meter wave Radio Telescope (GMRT) in MATLAB using PID and Discrete PID Controllers

Abstract: The proposed work focuses on simulating a control system for elevation position control of a Giant Metre wave Radio Telescope (GMRT) for turning the input commands into corresponding output positions. GMRTs are large parabolic dish antennas established by National Centre for Radio Astrophysics (Tata Institute of Fundamental Research) in India. The GMRT system has initially been modelled and evaluation of the system performance (using a reference step signal) has been done by using Proportional-Integral-Derivative (PID) and Discrete Proportional- Integral-Derivative (DPID) controllers.

Keywords: GMRT; Elevation; PID control; DPID control.
