【摘要】 在分析混沌形成的基础上,将变结构滑模方法引入到混沌理论中,通过它将处于混沌态的系统控制到稳定周期状态,然后,再用频谱方法测出待检信号的频率。所提出方法的新颖性在于去掉了以往混沌系统测量信号所需的策动力,而将待检信号作为策动力。经实验仿真发现:此方法与以往方法比较具有较高的分辨力。更多还原

【Abstract】 On the basis of analyzing the forming of chaos,variable structure control is applied in the chaos theory,through which a system which is in a chaotic state can be controlled to the stable periodic state;and then,the method of spectrum analysis is used to measure the frequency of the detected signal.The novelty of this method lies in getting rid of the driving force of former method which utilizes the chaos system for detecting signal;at the same time,the detected signal is used as the forced power.Simulation experiment shows this method has higher resolution than that of former method.更多还原
