| Research Abstract |
Aim of this study is to develop a novel concept of control systems utilizing stochastic resonance(SR) phenomena, which may be used in a wide variety of biotical systems, in order to possess artificial control systems to take on adaptable and robust ability. I fabricated ring oscillators of neuron-like elements with the SR phenomenon(SR element) in electronic circuit, and achieved the SR control system to assemble the oscillators. This control system shows unusual features. At suitable amplitude of noise is added to the system, the system shows adaptable behavior against some kind of system error. Furthermore, a study by using an FPGA device indicates that the parallelization approach of the SR elements provides the system robustness against element failures.
