Based on the linear time_invariant state space model of multirate digital control systems constructed by lifting techniques, this paper discusses the problem of simultaneous pole assignment of l plants by multirate input sampling digital control systems. Both the state space method and the polynomial matrix interpolation method are introduced to solve the problem. Through suitable transformations, the solution of the simultaneous pole assignment problem is resort to the solution of a number of linear equations. It is pointed out, simultaneous pole assignment of l plants is generally solvable by a static output feedback mutirate digital controller, if the input sampling rates of the multirate digital control system satisfying certain conditions.
