✦ Synopsis

ARSTRACT : A simple method is proposed for order reduction of linear continuous systems with real distinct eigenvalues. The steady state parts qf the unit step responses of the original and reduced-order models are matched in this method. Zeros are synthesized by minimizing the error between the transient responses, where as dominant poles are retained. An example is solved to illustrate the superiority of the method over some existing ones.

This paper proposes reduced-order estimation technique by the recursive least-squares filter and fixed-point smoother in linear discrete-time systems, given output measurement data. The estimators require the information of the system matrix, the observation vector of the signal generating model and
