T he aim of designing observer is to r ebuild the states through input and output . A suitable decay rate which is r elevant to the situtation of poles from estimated xd to real x is important . How ever, observ ers w ith accurate pole-placement of ten can no t satisfy other performance indices. In this paper, the reg io nal pole assig nment of reduced-order state observ er is discussed. It gives the unified alg ebraic parameterizat ion of these kinds of reduced-o rder state observers and the fundamental guidlines to design state observer so as to suit for mult iobjectiv e performances.
