By considering the rapid growth of microcomputer technology, it is now possible to implement various control algorithms into a microcomputer and to use it as a single-loop digital controller. This paper considers a design of a digital controller which achieves an arbitrarily specified closed-loop response. A linear equation is obtained for unknown parameters of such a controller based on series expansions of relevant pulse transfer functions. Some examples are given to show the characteristic features of the method.
