For a class of single-input / single-output linear systems with variable operating points, the stabilization problem is studied. The controlled system is expressed as a regular and stable linear decomposition of the approximation decomposition of the transfer function at two typical operating points. A design method of interpolation-type stabilization controller is given, which gives the necessary and sufficient conditions for the controller to stabilize the controlled object. In this paper, we prove that the proposed controller in [1] and [2 ~ 4] Compared with the proposed interpolation controller, the proposed controller can stabilize a wider range of controlled objects.
