In this paper we propose a reusable framework for a known engineering problem: Feedback control systems. Feedback systems are commonly described in terms of block diagrams and have different implementations according to the software system designer. The proposed framework is constructed using software design patterns as its building blocks. The Unified Modeling Language (UML) notation is used for specifying the framework class and collaboration diagrams. The framework is represented in the design level to be reused as an initial step in designing feedback control applications. An instantiation of the framework in a sample application is illustrated to show the flexibility and simplicity of using the framework.
