Adaptive Phase Control Method with Restrictive Conditions for Coupled Nonlinear Oscillators Array

研究了一类耦合非线性振荡器阵列的相位自适应控制方法,提出了一种基于LMS算法的,带约束条件的相位自适应控制方法,理论分析和仿真结果表明,该算法克服了振荡器频率控制参量在递推过程中引起系统不稳定的缺点,能实现大相位差的相位自适应控制。同时,还给出了利用耦合锁相环阵列内部信号实现阵列相位自适应控制的方案。

Adaptive phase control method of coupled nonlinear oscillators array was studied. When traditional LMS algorithm was used in coupled nonlinear oscillators array, the recursion of oscillator frequency might make the system unstable.A novel adaptive phase control method with constraint condition based on LMS algorithm was proposed. Theoretic and simulation results show that, by applying constraint condition on the recursive process of LMS algorithm, the array is always stable and larger phase differences can be obtained.At the same time, an adaptive phase control system configuration based on coupled phase locked loop array was proposed.
