This paper shows that two or more switched linear systems can generate chaotic dynamical behaviors by an appropriate switching rule as they at least consist of a controEable system and an unstable system with the expanding property.According to the results in the reference(Xie,L.L.,Zhou,Y.,and Zhao,Y.Criterion of chaos for switched linear systems with antrollers.International Journal of Bifurcation and Chaos,20(12),4105-4109(2010)),a nonlinear feedback gain is needed to generate chaotic dynamics.A linear feedback control is usually used to approximate the nonlinear one for simulation.In order to obtain the exact control,as a main result of this paper,the controller is constructed by Russell's result,and a block diagram is included to interpret the realization of the controller.Numerical simulations are given to illustrate the generated chaotic dynamical behavior of the switched linear systems with some parameters and show the effects of the constructed controller.
