Abstract :
An improved design method of PRBS signals for multivariable system identification is proposed. The approach sets different delay intervals to different channels instead of a unique delay interval. The minimal periodic length of PRBS is nearly the sum of the settling time of each channel. Consequently, a modified correlation analysis method is also put forward to identify the process model of multivariable system. The simulation shows that the proposed method can effectively shorten the periodic length of PRBS for multivariable system identification
