A source switching planning method for the feed support system of FAST

Abstract

The paper relates to a source switching planning method for the feed support system of the Five- hundred-meter Aperture Spherical radio Telescope (FAST). The source switching is to change the feed receivers from the current point to the starting point of the next observation. For solving the unstable control problem of the existing source switching planning, this paper presents a new source switching method. This new method adopts a combination of a line segment and focal segment to realize the stable control of the six-cable-driven parallel robot. Through the simulation of the example, the velocity and acceleration planning that meets the planning conditions are obtained, and the smooth change is realized.
