It is well known that the class of all stabilizing controllers for a given plant can be synthesized by the use of a full-order observer-based controller, with internal feedback loop involving free parameter which possesses stable dynamics. However, it seems very difficult to synthesize a minimal-order observer-based stabilizing controller, because the innovation is equal to zero. From this viewpoint, a novel synthesis method of the stabilizing controller by the minimal-order observer is studied in this paper. The basic idea is to estimate a part of state variables by using an observer with a function of estimating unmeasurable inputs.
