Nonlinear Circuits and Systems

Dr. Damon A. Miller

Chaotic systems are deterministic; that is, their behavior is completely described by mathematical equations. In spite of this deterministic nature, the exact state of a chaotic system rapidly becomes unpredictable after it is "turned on." Thus chaotic systems provide a source of "deterministic randomness" that can be utilized in practical applications. A properly designed observer can be synchronized with a chaotic system for use in communication systems.

In collaboration with Dr. Giuseppe Grassi of the Department of Engineering for Innovation at the University of Salento and Drs. Bazuin and Severance and students at WMU, Dr. Miller is exploring novel chaotic systems and their electronic implementations. For details, please consult this information sheet

Research is conducted primarily in the Nonlinear Circuits and Systems Laboratory located in room A-211 of the WMU Collge of Engineering and Applied Sciences.

Example Projects

Benjamin VanDyken, D. Miller, and G. Grassi, A Modular Printed Circuit Board For Realizing Discrete-Time Chaotic Systems presented at the 2013 NASA Michigan Space Grant Consortium (MSGC) Conference. This printed circuit board provides a convenient implementation of a sample-and-hold circuit based approach to implementing discrete-time chaotic circuits (see for example Grassi and Miller, IEEE Transactions on Circuits and Systems, vol. 48, pp. 366-374). Thanks to David Kirklewski, Donovan Squires, and James Truszkowski for their contributions to this project. Mr. VanDyken is supported by the MSGC. image
