摘要: The effective generalized orthogonal polynomials (GOPs) expansion is applied to estimating the parameters of a single-input-single-output linear time-varying system. It based on integration operational matrix for GOPs, which can represent all kinds individual polynomial. Using concept GOP state function and control function, differential input-output equation converted into set overdetermined algebraic equations. unknown are evaluated by weighted least-squares method. An illustrative example given. Very accurate results obtained.
