Using feedback with prediction to control chaos , we also catch hold of the result of high - period , which has never been reached . the double feedback method is introduced to control the chaos and hyperchaos in a 2 - dimensions discrete system and the spatio - temporal open - flow models based on the method of the delayed feedback and the predict method . the condition under which chaos can be stabi lized could be educed by theoretical analysis 提出预测反馈控制与延时反馈控制组合的双反馈控制方案,并将这一方案应用到对离散系统的混沌和超混沌的控制以及时空系统中混沌的控制;从理论上分析了具体系统采用此方案控制,系统能控制住的解析条件;理论和数值计算的结果都表明,使用组合的控制方案极大地拓宽了系统可控制的参数范围,提高了控制质量,有利于实际应用。
Moreover , with the method of emerging hopf bifurcation of the system , the analytic conditions that the low - dimension continuous autonomous chaotic systems controlled by the project are given in theory . applying the conclusions we got to the practical systems , the method is shown by the theoretical description and numerical calculation that it is effective 其次,从实际应用出发,提出了一种增强型的延迟变量反馈控制方案,同样利用分析延迟系统产生hopf分支条件的方法,也给出了当用这种方案控制低维连续自治混沌系统时,在达到控制目标的条件下,控制参数间的一般解析关系。
