求系统的时域性能指标的函数，给定系统的数学模型，即可通过该函数计算系统的超调量、峰值时间、调整时间和上升时间，经测试非常好用。-system for the time-domain performance of the function, given the mathematical model, This function can be calculated by the overshoot, the peak time, adjus

求系统的时域性能指标的函数，给定系统的数学模型，即可通过该函数计算系统的超调量、峰值时间、调整时间和上升时间，经测试非常好用。-system for the time-domain performance of the function, given the mathematical model, This function can be calculated by the overshoot, the peak time, adjus

根据系统传递函数求系统时域性能指标，输入为阶跃信号-Transfer function evaluation system according to the system performance in time domain, the input step signal

在matlab中需要用到的函数stepchar，而matlab系统里面一般没有的-In the function stepchar need matlab matlab system which generally do not
