拟牛顿粒子群算法在非线性电路谐波平衡方程中的应用
APPLICATION OF QUASI-NEWTON PARTICLE SWARM ALGORITHM IN NONLINEAR CIRCUIT HARMONIC BALANCE EQUATION
摘要
Abstract
The nonlinear distortion of power amplifier can lead to intermodulation distortion and adjacent channel interference, which seriously impacts the performance of the system, so the quantitative description and analysis on amplifier model are quite important. Based on the study of previous nonlinear circuits harmonic balance analysis method, in this paper we combine the particle swarm algorithm with quasi-new-ton algorithm ( quasi-newton particle swarm algorithm) to solve the harmonic balance equation, and get the corresponding simulation analysis results. Results show that, the use of quasi-newton particle swarm algorithm improves the system convergence rate, and at the same time the new algorithm fits well with various indices of the actual amplifier, this has good reference value for nonlinear circuits analysis.关键词
