A simple method for estimation of parameters in first order systems

Abstract

A simple method for estimation of parameters in first order systems with time delays is presented in this paper. The parameter estimation approach is based on a step response for the open loop system. It is shown that the estimation method does not require a complete step response, only a part of the response and the steady state value of the system before the step is applied. Further, for calculation of the time delay, it is also required that the time for the step is known.
