摘要
混沌理论作为一门新学科已经引起了世界各国科学界的重视,是近年来非线性科学领域的热门学科。混沌系统的初值敏感性和长期不可预测等一系列特点使得混沌理论可以应用于包括检测在内的很多领域。介绍基于混沌理论检测技术的国内外研究现状,主要包括基于Duffing振子的频率测量;基于初值敏感性的电压、电阻、电容、电感的测量;基于猎取法的临界值检测;基于MWM算法的信号分离技术;基于Feigenbaum映射的灵敏度测试等。对各种测量原理进行了评述,对研究现状进行了评价,并提出了进一步研究的重点。
The sensibility of initial value and unpredictability makes the chaos theory applied to a lot of realms that include detection technology. The domestic and international researching development chaos theory is introduced. It includes frequency measurement on Duffing oscillator, voltage and capacitance measurement on sensibility of initial value, critical value detection based on shooting method, isolation technique of signals on MWM algorithm, and sensitivity testing on Feigenbaum map. It narrates various principles of measurement and appraises researching development, and puts forward the further emphasis.
