Abstract: The conventional chaos control is only to reach single control objective at each time. Different control objective only can be realized at another time. Obviously, that is not enough for applications of chaos control, especially for chaotic connected complex network . Therefore a new research direction of control chaos ― multi-objective control (MOC) is naturally raised and needed in practical applications, such as in communication engineering, biological systems, social networks and so on since these systems have more than one unstable equilibrium and infinite unstable periods or time-space patterns . In this speech, we not only introduce some effective control method, but also propose a global linear coupling and combined with local feedback method to realize multi-objective control method for any chaotic connected complex network. To demonstrate the method effectiveness and its potential applications, I will take two typical examples: beam transport network (BTN) with halo-chaos and Lorenz chaotic connected network.
