    Abstract

    This paper covers in detail the issues related to parameter estimation of open loop dynamics of fly-by-wire aircraft/control systems from closed loop data. System identifiability aspects in the closed loop and the effect of various feedback types on the parameterisation of the system matrices are reviewed. The methods commonly employed for the detection of collinearity in the data are discussed. A brief discussion of the common methods used for analysis of unstable/augmented aircraft are given.Also, controller information based identification method (CIBM), which utilises knowledge of the controller in the analysis, is presented. The discussion is followed by numerical results of application of the techniques to simulated data.
