开关调制
Examples
- In the second place , controlling using strategy of system parameter switching modulation in two hyperchaotic circuits is studied
其次，采用系统参数开关调制策略，研究了两个超混沌电路的控制问题。 - Correlation characteristic of chaotic sequences have been studied . it demonstrate that chaotic sequences have the same characteristics as chaotic signal . replaced the random signals with chaotic signals , all kinds chaotic switching modulation mode can be obtained
将著名“蔡氏电路”产生的混沌开关调制信号用于buck型dc dc变换器开关的调制控制，使其工作在基于混沌的随机模式。 - Passive measure include : filter , fielding , earthing , bypass , decoupling etc . positive measure have resonant switching modulation ( include soft switching modulation ) , random switching modulation and chaotic switching modulation which be studied in this thesis
从源头上减小电磁干扰的方法有：各种谐振开关技术(包括软开关技术) 、随机开关调制技术、以及本文研究的混沌开关调制技术等。 - Chaotic switching modulation signals generated from different chaos sequences have been used to control smps . the effect of reducing the level of emi be compared . simulation results demonstrate : in the cpwm and cppm , chaos sequences generated from henon map is superior to the one generated from chua ' s circuit at lower multiples of switching frequency on reducing the level of emi ; in the ccfmfd , it has contrary results ; in the ccfmvd , chaos sequences generated from chua ' s circuit is superior to the one generated from henon map
仿真结果表明： cpwm和cppm模式下， henon映射混沌序列在较低次谐波处降低emi水平的效果要好于蔡氏电路混沌序列的效果。 ccfmfd模式则有相反的结果。对ccfmvd模式，蔡氏电路混沌序列比henon映射混沌序列降低emi水平的效果明显要好。 - At first , a method for controlling chaos is studied , which is based on phase switching modulation . the n - scroll chua ' s circuit is controlled to its fixed point as well as periodic orbits by using switching modulation on one its phase . its mechanism of control is analysed using the change of the max lyapunov exponent when the system is controlled
首先，通过对多涡卷蔡氏电路中非线性特性函数的相位进行开关调制，把多涡卷蔡氏电路由混沌状态控制到其平衡态和周期轨道，并用控制后系统的最大lyapunov指数随时间的转变阐述了其控制机制。
