Amoung the various methods used for determining the process dynamics, the method using ccross-correlation function seems useful if the white noise can be available as a test signal. In this paper, M-sequence signal picked out among the binary quasi-random signals is used instead of the white noise and the error caused by using this input signal is analysed in the time domain and frequency domain. Test was made on the first and second order lag systems as well as on a distributed parameter system, using the M-sequence signal generator designed by the authors. The results were in fairly good coincidence with theoretical results. This method using the binary quasirandom signal appears very useful and promises future applications in adaptive control systems.
