Chua circuit is a nonlinear circuit that shows complex dynamical behaviour including chaos. In chaos theory, the principle is known as‘Butterfly Effect’ where a small change in theinitial condition will cause large difference in the result. In this paper, the range of value of a resistor that cause chaotic behaviour is identified. A mathematical modelling is derived from the Chua’s circuit and represented in state-space equation. Then, a state-feedback controller is conFig.ured to stabilise and synchronise the slave system for two cases of reference input, that are, constant and chaotic signals. The output results showed the slave system follows the mastersystem’sbehaviour with zero synchronisation error.
