The overall objective of the proposed research is to examine the feasibility of low cost, innovative and intelligent control methods requiring minimum power or propellant for attitude control and/or autonomous formation maintenance. In order to investigate these issues and foster the development of novel and innovative technologies, the proposed research will focus on two primary objectives: attitude dynamics and control, and formation dynamics and control. The first objective of the research is to examine issues encountered in attitude dynamics and control systems. Several low cost methods will to be studied. These include controls based on environmental forces (i.e., solar radiation pressure, aerodynamic force, magnetic force, and gravity force) and combinations of these forces. Dr. Kumar's previous work in these areas, including the application of tethers and fluid rings for attitude control, will be extended. In the next objective, Dr. Kumar's research on formation control methods based on thrusters and environmental forces will be further developed and applied to formation keeping and reconfiguration. This research will also include coupled attitude and formation dynamics and control.  The applicant's research on robust and intelligent formation control strategies, based on linear and nonlinear controllers will be extended and applied to both the objectives. The feasibility of the proposed methods will finally be tested via computer simulation and ground test.Dr. Kumar anticipates that the outcome of this research program will lead to the development of innovative technologies for attitude and formation control of satellites. In addition, the proposed research will significantly contribute to the training of researchers and scholars in leading-edge technologies to meet the needs of the Canadian space and high-technology sectors.

拟议研究的总体目标是研究用于姿态控制和/或自主编队维护的低成本、创新和智能控制方法的可行性，这些方法需要最少的功率或推进剂。为了研究这些问题并促进新技术和创新技术的发展，拟议的研究将集中在两个主要目标：姿态动力学和控制，以及队形动力学和控制。这项研究的第一个目标是检查姿态动力学和控制系统中遇到的问题。将研究几种低成本的方法。这些控制包括基于环境力(即太阳辐射压力、空气动力力、磁力和重力)以及这些力的组合的控制。库马尔博士之前在这些领域的工作，包括用于姿态控制的系绳和流体环的应用，将会得到扩展。在下一个目标中，库马尔博士对基于推进器和环境力的编队控制方法的研究将进一步发展，并应用于编队保持和重构。这项研究还将包括姿态和编队动力学与控制的耦合。随着申请人对基于线性和非线性控制器的鲁棒和智能编队控制策略的研究，将扩展并应用于这两个目标。最后通过计算机仿真和地面试验验证了所提方法的可行性。库马尔预计，这一研究计划的成果将导致卫星姿态和编队控制创新技术的发展。此外，拟议的研究将大大有助于对研究人员和学者进行前沿技术方面的培训，以满足加拿大空间和高科技部门的需求。
