Abstract

The concept of robustness is examined and discussed in the context of rotorcraft system identification and modelling. A classification of robustness issues is proposed involving experimental design aspects, identification techniques, model structure estimation, parameter estimation and the robustness of the complete mathematical model resulting from the application of identification processes. Associated tests of robustness are proposed and a set of special recommendations is presented for each of the aspects considered. Within these recommendations particular emphasis is placed on the need for a good user interface which fully exploits the use of computer graphics and for reliable tools for the assessment of model structure. The need for preliminary flight tests to characterise the dynamics of the system and thus guide the design of identification experiments is also emphasised. A further recommendation is that design criteria should be established for verification inputs.
