VLSI Hardware Design of Generic MIMO Controller with Application in Satellite Orbit Control
Journal Title: International Journal of Computational Engineering and Management IJCEM - Year 2014, Vol 17, Issue 1
Abstract
This paper deals with the attitude and orbit control of a satellite by applying MIMO quantitative feedback approach. The objective is to design a set of proper controllers in presence of unknown disturbances and parametric uncertainties for a nonlinear MIMO system. The controller goal is to control the rotational speed of reaction wheels to adjust the satellite in desired course. In the present work, we have followed a different and convenient approach to design a generic MIMO controller that can be used for any applications. The design strategy relies on system parameters that can be encoded in the form of digital bit patterns and further control schemes can be easily designed based on that information. We further show how this generic MIMO controller can be used to control the satellite in its orbit which is considered to be a difficult problem. We solve various kinematic equations of motion of the satellite to arrive at control laws and then find the desired control scheme for our MIMO controller. The complete implementation of the design is achieved using VHDL and targeted for Virtex 6 FPGA using Xilinx ISE Design Suite
