In the parametrization, we investigate the number of required parameters. We consider single-input single-output systems in this paper. By the investigation, we find, on the discrete-time systems without the unit-delay element, three cases that are (1) there exist plants which require only one parameter and (2) two parameters, and (3) the number of parameters is at most three.}, journal = {International Journal of Electrical and Information Engineering}, volume = {11}, number = {6}, year = {2017}, pages = {778 - 782}, ee = {https://publications.waset.org/pdf/10007548}, url = {https://publications.waset.org/vol/126}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 126, 2017}, }
