{"Image DocumentName": "Summary 13&14The engineer\u2019s aim is to minimise the amount of data collected to identify the parameters sufficiently accurately.", "Image ImageDescription": "Signal magnitude should be as large as possible to improve the signal/noise ratio and to minimize the parameter covariances. However, the signal should not to large enough to violate any system constraints or to make the unknown system significantly non-linear. Signal type & frequency must be smooth enough not to exceed any dynamic constraints, however the dynamics must excite any potential dynamics. When parameter estimation is on-line, this imposes additional constraints as the signals must be sufficiently exciting for each time period. Exponential-forgetting can be used to track time-varying parameters, but previous comments must hold.
