An Improvement of Correlation Analysis in System Identification

Zhao Zhengmin

Abstract

Correlation analysis, using pseudo_random binary sequence as input, is an effective method to identify the impulse response of control. An improvement of this method, i.e., increasing the length of M sequence after fixing the number of discrete values of impulse response to improve the precision, is presented. Simulation results demonstrate the validity of this means.
