| Abstract: | A method for estimating the modelling errors of a process using closed-loop data is proposed. The theoretical analysis and implementation of the method are illustrated. A new algorithm of system identification which identifies the plant as an impulse response sequence or a transfer function model using the output of a feedback control system is derived. An illustrative example which shows the use of the proposed method for the estimation of modelling errors and its application to closed-loop identification is also included. |
