Nonlinear System Identification Study. Part I. Implementation Feasibility Study.
Abstract
The implementation feasibility of a nonlinear system identification technique is evaluated in this report. The identification technique uses a 'black box' approach requiring measurements only at system input and output terminals and is applicable to weakly nonlinear systems whose behavior is adequately characterized by a finite Volterra series. Three hardware implementations of the identification technique are postulated and their respective performances are evaluated. The impact of A/D converter quantization error, non-ideal amplifiers, multipliers and integrators on performance of the identification process is assessed. Performance requirements for each of the three implementations are derived via simulation and analysis. The feasibility of implementing the technique using commercially available state of the art components and measurement equipment in each implementation is assessed. RADC-TR-79-199, Part II, A computational complexity study of the identification technique processing to determine the class of nonlinear systems to which the technique can be practically applied will be published at a later date.
