Shinen2 principally has three units, CCU (Communication Control Unit), PCU (Power Control Unit) and SCU (Shinen2 Control Unit). This paper describes how to control PCU and functions of redundancy for PCU in space by SCU’s function. | Journal of Automation and Control Engineering Vol. 4, No. 5, October 2016 A Redundancy and Operation of Power Control System for a Deep-space Small Probe Fumito Kuroiwa and Sidi Ahmed Bendoukha Department of Applied Science for Integrated System Engineering, Graduate School of Engineering , Fukuoka, Japan Email: {o350912f, o595904a}@ Kei-ichi Okuyama Kyushu Institute of Technology, Fukuoka, Japan Email: okuyama@ Hiroki Morita Kagoshima University, Kagoshima, Japan Email: k5977380@ Masanori Nishio Aichi Institute of Technology, Aichi, Japan Email: nishio-masanori@ being hit with radiation. This paper is focuses on the power control units and is written to distribute the power to each electric component and observed systems of the power control unit by other control units. Abstract—a small deep space probe, Shinen2 was produced by the Kyushu Institute of Technology in collaboration with Kagoshima University. Shinen2 was lunched by an H2-A rocket as a piggy-back space probe with Hayabusa-2 of JAXA’s probe in 2014. Shinen2 is exploring in the deep space beyond the moon. Shinen2 has three missions: the first mission is a structure mission, Shinen2 is composed of CFRTP (Carbon Fiber Rein Thermo Plastics), the second mission is a communication mission by WSJT (Weak Signal radio communication by Joe Taylor, K1JT), and the third mission is a measurement mission; Shinen2 has radiation sensors which measure radiations in deep space. Shinen2 principally has three units, CCU (Communication Control Unit), PCU (Power Control Unit) and SCU (Shinen2 Control Unit). This paper describes how to control PCU and functions of redundancy for PCU in space by SCU’s function. II. SHINEN2 The small, deep-space probe Shinen2 was developed under collaboration with the Kyushu Institute of Technology and Kagoshima University [3]. Fig. 1 shows the outline of Shinen2, which is classified as a small probe. Index Terms—space engineering, .
