以一维驱动非线性漂移波方程为模型 ,研究了利用外加周期信号成功地对时空混沌进行非反馈控制过程中的相同步.在驱动波坐标系中 ,系统可以被变换成一组在周期势中运动的耦合振子模式,这些模式通过相同步被控制信号逐一控制.研究发现 ,内部模式对外加周期信号的响应方式有2种 一些模式表现出锁频 ,另一些模式则观察到了一种特殊的无锁频的相同步-To drive one-dimensional nonlinear drift wave equation as a model to study the use of periodic signal plus successfully non-spatio-temporal chaos in the process of feedback control phase synchronous. In wave-driven coordinate system, the system can be converted into one group in the periodic potential in movement coupled oscillator model, these models are controlled through the phase synchronous control signal one by one. The study found that the internal model of the external periodic signal increases in response to the way the two kinds of models to show lock, some other mode observed a special kind of without frequency-locking of the phase synchronous
