Original abstract
An estimation of Simulink model parameters is very important problem in field of system identification in mechatronics. This paper describes features and advantages of the New Parameter Estimation Tool developed with respect to particular engineering needs. Among other things, the tool allows to use the arbitrary combination of a model and a measured data for the construction of cost function of the optimization process. This enables to formulate various tasks briefly outlined in this paper including comparison of several candidate models or performing estimations of models with shared parameters. Furthermore, all temporary simulation results are stored and later can be browsed and viewed by user. This enables to get very clear visual insight into the estimation problem and especially increases the usefulness of the Brute force method use. Finally, the tool allows to cope actively with the problem of initial guesses of an optimization method. As a result, user can automate and control parameter estimations for time-consuming and demanding problems
