| Description/Abstract | System identification is used in many engineering applications. Most of these identification problems can be solved using one of the many time domain methods that have been studied and well developed in the last 15 years. However, in practice frequency response data, or Bode plots, may be the only data available to the engineer. Also, in some applications a time domain model of the system is not necessary. Instead, the engineer wishes to gain a general knowledge of system response. In these instances a frequency domain system identification technique may be more appropriate. For this particular project there was an interest in estimating the coefficients of a Laplace transform transfer function system model. The transfer function model would aid in the design of machine tool control systems. Several available parametric frequency domain identification methods were studied and three computer codes were chosen for further development as representatives of different approaches to the solution of the problem. |
