针对当前单向链式网络的激光控制精度较差、收敛性不好等问题,提出一种基于Logistics映射混沌性扰动抑制控制的单向链式网络激光控制器设计方法。对控制模型进行被控对象描述和控制约束参量分析,采用Levenberg-Marquardt(LM)算法构建激光控制器的前馈控制规律,采用Logistics混沌映射进行倍周期分岔扰动,以抑制控制输出的测量误差,实现单向链式网络的激光混沌性控制。实验结果表明,采用该控制方法进行单向链式网络的激光控制,输出测量误差小,稳定性较好,鲁棒性较高。
In order to solve the problem of poor control accuracy and poor convergence of current one-way chain networks, a design method of one-way chain network laser controller based on the chaotic disturbance rejection control of Logistics map is proposed. The control model is described by object description and control constraint parameter analysis. The Levenberg-Marquardt (LM) algorithm is used to construct the feedforward control law of laser controller. The chaotic map of Logistics is used to perform the periodic bifurcation perturbation to suppress the measurement error of control output , To achieve laser chaos control of unidirectional chain network. The experimental results show that laser control of the one-way chain network using this control method has small output error, good stability and high robustness.
