Indirect parameter estimation of continuous-time systems using discrete time data. In 29th Annual Conference of the IEEE Industrial Electronics Society. Roanoke, USA. p.600-605. ISBN 0-7803-7906-30-7803-7906-3http://hdl.handle.net/10198/2219This paper addresses the problem of parameter estimation of continuous-time systems using samples of its input-output data. We propose a method based on the bilinear transformation to obtain an equivalent discrete-time model. Introducing a new polynomial pre-filter it .is possible to compute the physical parameters via inverse mapping between the discrete-time and the continuous-time models. A simulation example is given to illustrate the noise effects in the parameter estimation results. Using experimental results, we demonstrate the ability of the estimator. to handle real measurement problems.engconference object2010-02-06
