IDENTIFICATION OF TIME-VARYING NONLINEAR-SYSTEMS USING CHEBYSHEV POLYNOMIALS

[摘要] This paper is devoted to an identification of time-varying nonlinear systems using Chebyshev polynomials of the first kind. For systems being linear relatively unknown functional parameters, a method of approximate determination of these parameters has been worked out. As the identification problems are ill-posed to solve the obtained redefinite system of linear algebraic equations, a regularization method is used.
