Stability of distributed 3-D systems implemented on grid sensor networks using floating point arithmetic
Buddika Sumanasena, Peter H. Bauer · 2011
In this paper, stability of distributed 3-D systems implemented in sensor networks using the Givone-Roesser and the Fornasini-Marchesini state space models under floating point arithmetic is studied. Nonlinearities caused by floating point number representation schemes used for in node computations and inter node communication are modeled. Stability of the system is analyzed with special consideration given to the influence of internode communication on system dynamics. A necessary and sufficient condition for global asymptotic stability under floating point arithmetic is established. Simulation results are presented to illustrate the theoretical results.
