自动控制原理第五章频域分析法 - 频率法2. 峰值频率 ω r 是指幅频特性最大值 M r所对应的频率值。 ω r 大 , 表明系统的快速2性好。对于二阶系统 , ω = ω − ξ 。r n1 23. 闭环系统的带宽 ω b 定义为幅频特性下降到 0.707M(0) 时所对应的频率。一般情况下 , 系统的阶跃响应速度与 ω b 成正比 , 调节时间与 ω b 成反比 , 因此 , 在保证系统的合理时域指标的前提下 , 总是希望系统有较大的带宽。
自动控制原理第五章频域分析法 - 频率法对于一阶系统 , 若传递函数为1Φ ( s)=Ts + 11系统带宽频率 ωb=T系统调节时间ts= 3T= 21ω b
