Chaos Synchronization of Nonlinear Bloch Equations Based on Input-to-State Stable Control

In this paper, we propose a new input-to-state stable （ISS） synchronization method for chaotic behavior in nonlinear Bloch equations with external disturbance. Based on Lyapunov theory and linear matrix inequality （LMI） approach, for the first time, the ISS synchronization controller is presented to not only guarantee the asymptotic synchronization but also achieve the bounded synchronization error for any bounded disturbance. The proposed controller can be obtained by solving a convex optimization problem represented by the LMI. Simulation study is presented to demonstrate the effectiveness of the proposed synchronization scheme.

一种汽车制动不同步的方法分析研究

针对汽车制动时前后轮制动力分配不均产生的制动不同步问题,先对汽车制动时进行受力分析,得出制动时不同步的原因及结果。然后对不同步控制方法的影响因素和方法的分析,得出几种典型控制技术。最后在分析结果的基础上,通过MATLAB进行建立变速器变速运动规律模型建立,以及模糊控制模型、参数调试和仿真。最后,着重分析汽车的变速器调节制动力分配后的制动过程,得到良好的ABS模糊制动控制效果,为进一步制动控制研究打下良好基础。
