A general response system control method for synchronization of continuous scalar chaotic signal is presented. The proposed canonical genera/response system can cover most of the well-known chaotic systems. Conversely, each of these chaotic systems can Mso be used to construct the genera/response system. Furthermore, a novel controller of the proposed response system is designed based on backstepping technique, with which the output of the genera/response system and the given continuous chaotic signal can synchronize perfectly. Two numerical examples are given to illustrate the effectiveness of the proposed control method. 相似文献

研究了单周控制Buck变换器中的降频现象,并给出了降频现象发生的临界条件以及电感电流断续导电模式(DCM)与电感电流连续导电模式(CCM)的临界条件.研究结果表明,降频现象的发生是由于复位积分器的输出电压在n个时钟周期内不能达到参考电压Vref,使得它无法在n个时钟周期内复位,只有在n+1个时钟周期内复位. 值得注意的是,在任一工作频率下,变换器无论工作在CCM还是DCM,均处于稳定状态;在主电路参数及时钟周期不变的情况下,DC

以不连续运行模式下的电流反馈型Buck-Boost变换器为例,导出了一类具有三段形式的分段光滑迭代映射方程,数值仿真得到了输入电压变化时的分岔图.结果表明,发生分岔时映射雅可比矩阵的特征值以不连续的方式跳跃出复平面上的单位圆,而且映射总有某个或某些轨道点位于相平面中不同区域的边界上,即映射随输入电压的变化会发生边界碰撞分岔现象,如由周期态到周期态以及由周期态到混沌态的分岔.

A novel adaptive observer-based control scheme is presented for synchronization and suppression of a class of uncertain chaotic system. First, an adaptive observer based on an orthogonal neural network is designed. Subsequently, the sliding mode controllers via the proposed adaptive observer are proposed for synchronization and suppression of the uncertain chaotic systems. Theoretical analysis and numerical simulation show the effectiveness of the proposed scheme. 相似文献
