Mode Analysis of a Tubular Structure of Coupled Fifth-Power Non-Linear Oscillators for Large-Intestinal Modelling

摘要

A matrix Krylov-Bovolioubov linearization technique was used to extend mode analysis to a tubular structure of oscillators, representing human large-intestinal electrical behavior. The method of averaging was used to calculate the stationary amplitude values. Mode stability was investigated for zero state, single modes, and double nonresonant modes. Theoretical results for a case with four rings each having three oscillators compare favorably with an experimental investigation, using electronic implementation of van der Pol oscillators.
