Question

The Magellan spacecraft (as shown in Figure 2), also referred to as the Venus Radar 5. May 4 1,035-kilogram robotic space probe launched by NASA on Mapper, was a 1989, to map the surface of Venus using Synthetic Aperture Radar and measure the planetary gravity. The position control system for the spacecraft is governed by the following equations: d2p dp +4p +2 dt2 dt =r-p de 0.602 dt 71 The variables involved are as follows: desired platform position r(t) p(t) actual platform position (0)a amplifier output voltage amplifier input voltage (1)a motor shaft position e(t) a) Sketch a signal-flow diagram of the system, identifying the component parts and their transmittances (5 marks) Determine the transfer function of the system b) (5 marks) POMARD tQurENT E MODULE PROPLLSON MODLLE nOCKET ENGE ANTEN THEMAL CONERO LOUNERS SOLAR PANEL DVE NID CABLEAP NEA AUMTE ANTENA SOLAR PANEL Rajah 2: Kapal Angkasa Magellan Figure 2: The Magellan Spacecraft
