Abstract :
A parameter estimation problem is considered for state equations of linear time-invariant systems. Under a certain condition, it is shown that the output of the system can be asymptotically described by a linear combination of output estimates which are generated by suitable multiple observers. An identification scheme for the weights of the linear combination is proposed. The obtained weights determine the parameter values to be estimated
