We have described a recursive parameter estimation method for first-order systems. The method reinforces and integrates mathematical and statistical techniques in an engineering experiment. In addition, students can simulate the convergence of the algorithm with noisy data, compare the model output with the measured data, test the convergence with various initial conditions, investigate the suggested variation of the algorithm for reduced computation, determine the effects of sampling time and the number of iterations on the convergence of the algorithm, and investigate the loading effects of the dSPACE hardware. The experiment is currently accessible via Internet if a remote user logs into a computer located at Bucknell University. We are developing a World Wide Web interface that will permit a remote user to execute the experiment and retrieve the measured data.
