Abstract :
This paper presents a method for parameter estimation of two-mass mechanical loads. A discrete-time polynomial model with an output error (OE) structure is used in parameter estimation. Four different identification setups are obtained when open-loop estimation and various possibilities of choosing the input and output signals in closed-loop estimation are considered. All four setups are analyzed, and the identifiabilities are compared. It is discovered that all four identification setups can be used to obtain reasonable parameter estimates.
