| 中文摘要 |
| A.Duchateau et al的多模型控制策略是一种改进的OGY方法,为扩大控制器在吸引子中的作用范围,需要在混沌系统的一条无控收敛轨道上设置一系列的局部线性模型,由线性反馈控制律把混沌系统引导到不动点,这要求控制器的结构和控制量的大小是可变的.本文应用人工免疫算法的参数和结构双重可塑性来产生多模型控制策略控制律,由此提出了一种新的混沌控制方法.对Hénon映射仿真的结果表明:与其他方法相比,新方法能在较短的混沌暂态时间内把系统控制到预定轨道.因此,基于人工免疫算法的混沌多模型微扰控制方法能对混沌系统实施有效控制,且能够应用于系统全局动力学模型未知而仅获得实验数据的情况. |
| 英文摘要 |
| The multi-model solution proposed by A. Duchateau et al is a further extension of the OGY method. In order to increase the zones of effective control (ZECs) of the attractor, a series of local linear models and control laws was positioned along an uncontrolled convergent trajectory that could direct the chaotic process towards its fixed point. So, controllers with both variable structure and parameter were required. A new control method was presented that the control laws of multi-model solution were generated by artificial immune algorithm to obtain double plasticity of parameter and structure. The simulation results showed that the new method could control the chaotic system towards its desired trajectory in less chaotic transient time than it used to be. The proposed approach is applicable to the systems with unknown dynamic model and known experimental data. |
