Error analysis of continuous-time system identification using laguerre basis

Continuous-time system identification is desirable and necessary from several fine characteristics of continuous-time models. It was already shown that a continuous-time system is identified effectively by means of the transformation of the continuous-time system into a discrete-time system using the generalized orthonormal basis. This paper proposes the error analysis of continuous-time system identification using the Laguerre basis, the special case of the generalized orthonormal basis. This paper also argues how a parameter of the Laguerre basis should be chosen correctly to improve accuracy of system identification.
