During the design process of the DC motor composite positioning control system (CPCS), in order to solve the contradiction between the positioning accuracy and the stability, we introduce the equioscillation and equiprecision lines in the root locus plane, analyze and compare root locus maps, the frequency characteristics, and the dynamic responses for PID and CPCS on MATLAB. The results show: within the high-order control system root locus configuration boundary, there always exist three specific boundaried subspaces. Under the condition of simplifying the transferring function to fifth-order from using zero, poles cancellation method, the subspaces’ controllability and observability are not changed. The determination of status feedback matrix K and estimator gain L for the high-order control system can be transformed to solving the third-order dynamic equations for specific boundary conditions, and by constructing the dynamic regulator or compensator achieve zero-pole optimal configuration.
