摘　　要：采用驱动嵌入参数间断渐变的控制方法,在混沌系统调控中有效地实施动力学特征有序变化的时空行为的追踪控制研究。数值研究结果表明:在驱动信号的作用下,信号强度的调谐诱发混沌系统运动行为的序列演变特征。获得受控时空混沌的各类数值模拟结果。We have effectively implemented the study of the tracking control of space-time action for the controlled chaotic system, which concerns the orderly change of dynamic feature, using the gradual change method of driving parameter. Numerical simulation results show that the evolutional alignment of the chaotic system relys on the harmonious of signal strength when change scope of the parameter is a large region. Some simulation results of space-time chaos have been obtained.
