Experiments on node-to-node pinning control of Chua's circuits
Pinning controllability problems can be viewed as synchronization problems on augmented oscillator networks that incorporate the reference oscillator. In the paper, an experimental study of pinning controllability of coupled Chua's chaotic circuits is presented. Static and node-to-node pinning control is analyzed through an in-house developed experimental platform comprised of three Chua's circuits coupled through all their states. The parameters experimentally varied in the work are: the total pinning control gain, the number of pinned circuits in case of static pinning control, the connection strength between the oscillators, and the switching frequency for node-to-node pinning control. The novelty of the platform is in the full state time varying coupling of the three circuits. Experimental results are supported by analytical findings. Global pinning controllability of an oscillator network through node-to-node pinning control is analyzed. Sufficient stability conditions on the overall control gain and maximum switching period for global pinning controllability of an oscillator network are established in terms of network topology, coupling strength among the oscillators, and properties of the individual oscillator dynamics.
