摘要
混沌粒子群算法较其它算法具有编程容易、精度高、收敛速度快以及不易陷入局部极值特点,以力反馈两级电液伺服阀为对象,对影响其稳定性及快速性的参数进行优化,在满足伺服阀稳定以及最佳阻尼比的前提下,通过提高伺服阀的固有频率、开环增益来提高伺服阀的频宽,进而提高伺服的稳定性和快速性。结果表明,混沌粒子群算法对伺服阀参数优化后,伺服阀的稳定性和快速性均得到改善。
Compared with the other optimization algorithm,Chaos Particle Swarm Optimization has the character of simple program,high accuracy and convergence,and difficult to get into the local extreme value,it mainly to realize serovalve＇s best rapid performance through optimized its parameters.Under the condition of insuring its stability and the best damping,in order to improve serovalve＇s stability performance and the frequency response,the paper tried to increase serovalve＇s frequency range by improving its natural frequency and open cycle gain.The simulation results shows that the stability performance and the fre-quency response all get improved after optimized the parameters of the serovalve by CPSO.
