On general control methodology for complex systems

By reviewing on comprehensive descriptions and definitions of complex systems, this paper concludes the key problems and the general characteristics of control of complex systems, by which the Emergence-Oriented Control methodology is briefly introduced. The methodology contains the following two principles for dealing with the key problems in the control of complex systems. Firstly, control strategies are dependent on emergent behaviors and the mechanisms producing those behaviors. The second is that the implementation of a control strategy is an open dynamic adjustment process between the control strategy and certain system emergent behaviors. As a general ontology, the Emergence-Oriented Control provides a well-established tool for identifying and resolving control problems in specific systems.
