Bounded-error uncertainty domain description for continuous-time state-space model

A method is introduced to determine the uncertainty domains of the estimated parameters for multi-input multi-output linear time-invariant continuous-time systems. This method uses a continuous-time subspace-based algorithm in order to identify the parameters of the system. This identification method is specific because the estimated state-space realisation is described with the help of a state-space canonical form. Then, a bounded-error approach is considered in order to characterise the uncertainty domains of the coefficients of the state-space matrices. A simulation example is included to demonstrate the efficiency of the developed method.
