说明：  使用MatlAB对控制系统进行仿真的例子很好好好(Use MatlAB simulation of the control system a good example of good)

非线性混沌工具箱，可以用来求解非线性系统的分叉、混沌等(Non-linear chaotic toolbox can be used to solve the nonlinear system of bifurcation, chaos, etc.)

Earthquake Engineering and Structural Dynamics(You can input any number of stores by giving the mass, stiffness and damping values. Input the gamma and beta values which are related to Newmark Integration Mtd. Press Newmarks Integration button to input the values. Input the any number of storey that you expected to see the deflection for particular Earthquake. Press “Storey No” button to get that number. If you like only, you will input the period and press “Period” button. Finally press calculate button to see final results. Also you can see the both graphs in log scales also.(Please right click on the graph as shown above). You may see what type of analysis method is used. (Average acceleration relation ship or Linear variation of acceleration).)

　Buck-Boost转换器转换周期轨道从混乱的状态,本文提出一种　　混沌控制方法通过改善电感电流和输出电压之间的关系。通过调整　　耦合强度,这种方法可以控制混沌周期2 Buck-Boost转换器,period-4,period-8轨道　　period-9轨道和周期3,时间6,不确定不稳定周期轨道(着)。(To transform the Buck-Boost converter the chaotic state to the periodic orbits, this paper proposes a chaotic control method by improving the correlation between the inductor current and the output voltage. By adjusting the coupling strength, this method can control the chaotic Buck-Boost converter to the period-2, period-4, period-8 orbits and the period-3, period-6, period-9 orbits, without determining the unstable periodic orbits (UPOs) in advance.)
