CONTROLLING CHUAS GLOBAL UNFOLDING CIRCUIT FAMILY

The self-unified and conventional feedback control strategy developed by the present author and his colleagues for the control of chaotic dy namical systems is extended from the Chua's circuit to its global unfo lding, driving the circuit dynamics from chaotic attractors to any des irable trajectories such as unstable limit cycles. A simple and realis tic sufficient condition for such controllability of the global unfold ing is derived. A similar sufficient condition for the controllability of the whole family of nonlinear dynamical systems that are topologic ally equivalent to the Chua global unfolding is also established.
