未来的传感器阵列将由相互作用的非线性组件组成,具有复杂的行为,没有已知的解析解。本文通过数值分析和解析分析,对预期行为提供了初步的认识。具体地说,将周期驱动的非线性Duffing谐振器弹性耦合到van der Pol振子的复杂行为作为具有局部连通性的这类单元的2D格子中的积木来研究。采用双时标法对双装置单元进行了解析处理,并对复杂动态运动的稳定性进行了分析。对这些单元通过最近邻相互作用耦合在一起的2D晶格的图案形成特性进行了数值分析,得到了适合于通过MEMS器件实现物理实现的参数。研究了全局同步和集群同步的涌现模式与系统参数和晶格尺寸的关系。
Future sensor arrays will be composed of interacting nonlinear components with complex behaviours with no known analytic solutions. This paper provides a preliminary insight into the expected behaviour through numerical and analytical analysis. Specifically, the complex behaviour of a periodically driven nonlinear Duffing resonator coupled elastically to a van der Pol oscillator is investigated as a building block in a 2D lattice of such units with local connectivity. An analytic treatment of the 2-device unit is provided through a two-time-scales approach and the stability of the complex dynamic motion is analysed. The pattern formation characteristics of a 2D lattice composed of these units coupled together through nearest neighbour interactions is analysed numerically for parameters appropriate to a physical realisation through MEMS devices. The emergent patterns of global and cluster synchronisation are investigated with respect to system parameters and lattice size.
