Abstract: Taking the road simulation system as a studied topic, a new approach was brought out to generate signal for system identification. A bottom triangle filter was constructed by the system characteristics. The worth of the filter was determined by the statistical attribute of practical signal. The expectative signal was obtained when the normal distributional white noise passed the filter. Using this signal to identify the system can improve the efficiency of system identification.
