“…The particular aircraft analysed in this experiment is an F-8 experimental fly-by-wire aircraft, and the numerical data describing its dynamics is taken from [4]. The results in figure 1 show that the continuous-time algorithm produces less accurate estimate than the indirect method.…”

This paper demonstrates the use of a continuous-time subspace model identification method, in the identification of MIMO state-space models. The measured input and output signals are assumed to be measured at regularly spaced sampling instances. The presence of both measurement, and process noise is considered. The proposed method gives a biased estimate of the system matrices, but we shall show how to minimise this bias by a proper choise of the lag used for the instruments. Finally, the applicability of the method is demonstrated in the identification of aircraft dynamics.

“…In engineering, the complexity can also be reduced with advanced control computer. For example, in y-by-wire aircraft, the handling characteristics of an aircraft can be altered by the ight control computer to be more usable for human pilots (Elliott, 1977). However, the development, and especially debugging, of safety-critical software systems is extremely costly (Blanchet et al, 2002).…”

“…Due to the memory and speed limitations of the flight computer, the practicality of the proposed designs were judged based on the feasibility of the algorithms required to implement the control law. Results of some successful proposed designs are summarized in the mini issue of the IEEE Transaction on Automatic Control [3].…”
