Abstract
This paper presents an indirect adaptive pole-placement algorithm for SISO noiseless systems under the assumptions that an upper bound on the plant order and a lower bound on the Sylvester resultant of plant polynominals are known. The algorithm consists of three parts; the identification of the plant, the calculation of controller parameters based on the triangulation of transfer matrix for the observable canonical state variable, and the generation of self-excitation signal. The global stability of the closed loop system is proved, and an numerical example is given to illustrate the effectiveness of the proposed algorithm.
