自动门:控制系统快速性

控制系统快速性

    为了裉好完成控制任务,控制系统仅仅满足稳定性要求是不够的,还必须对其过渡过
程的形式和快慢提出要求,一般称为动态性能,例如,对用于稳定的高射炮射角随动系统,
虽然炮身最终能跟踪目标,但如果目标变动迅速,而炮身跟踪目标所需过渡过程时间过
长,就不可能击中目标I对用于稳定的自动驾驶仪系统,当飞机受阵风扰动而偏离预定航
线时,具有自动使飞机恢复预定航线的能力,但在恢复过程中,如果机身摇晃幅度过大.或
    恢复速度过快,就会使乘员感到不适;函数记录仪记录输入电压时,如果记录笔移动很慢
或摆动幅度过大,不仅使记录曲线失真,而且还会损坏记录笔,或使电器元件承受过电压。
因此,对控制系统过渡过程的时间(即快速性)和最大振荡幅度(即超调量)一般都有具体
要求。
