            respectively. From the results presented, it could be observed that synchroni-
            zation was achieved by the convergence of the trajectories of the systems
            and error state variables to zero. Fast and exponential convergence of the
            error could be observed in all the different switches. The proposed control-
            lers, by virtue of the convergence, could be said to be effective. By applying
            the proposed controllers in this work added complexity, which translates to
            better security will be introduced into the communication system. The multi-
            switching component in this work can be used as a prearranged key in a
            secure communication system.


            15.6 CONCLUSION

            The multiswitching synchronization of two fractional order chaotic systems
            with different dimensions have been implemented using the method of active
            controls. Six possible switches were proposed and controllers designed for
            each of the six switches. Numerical simulations were carried out to test the
            effectiveness of the proposed controllers. From the results presented, the con-
            trollers were found to be effective by the convergence of the error dynamics
            to zero.
               However, there is the opportunity for further studies. Practical implemen-
            tation of the proposed controllers using electronic simulation is hereby
            recommended. Also recommended is the implementation of multiswitching
            combination and combinaiton combination synchronization of fractional
            order system with different dimensions. In particular, multiswitching syn-
            chronization of two-, three-, and four-dimensional fractional order systems is
            proposed.
