System identification via generalized block pulse operational matrices
Chi‐Hsu Wang, Richard S. Marleau · International Journal of Systems Science · 1985
Owing to the elegant properties of generalized block pulse operational matrices, a SID (system identification) matrix can be derived to identify transfer function coefficients of a linear time-invariant system from the unit step response data. The identification algorithm performs in a least-squares sense and can be recursive according to previous work. This approach not only yields satisfactory results but also provides a more precise and efficient method for the system identification problem.
