Combining the nonlinear control system theory and the aim of chaos synchronization, we designed a nonlinear feedback controller for synchronizing the scalar output signal of Chua's Circuits system.

An open-loop (direct) system operates without feedback and directly generates the output in response to an input signal.

As long as the pre-set current value and a good bonding time, the system based on current feedback signal auto - Regulation, will not be glued current thickness change and mold temperature rise.
