The study of simultaneously stabilizable problem of plant family

The simultaneous stabilization problem of a plant family with uncertainty parameter is considered. A controller which contains a parameter is designed to simultaneously stabilize two specified plants. The parameter in the controller can be obtained by using the theory of stability of a plant family system. So, the problem of designing a controller is converted into the problem of checking stability. We can design the controller simultaneously stabilizing the plant family and determine the parameter in the plant.
