A circuit simulation of the conversion of the oscillation state near Hopf bifurcation is performed using time-delayed feedback control techniques. The system consists of a target oscillator and a control oscillator coupled with each other. Both the target and controller we used are described by the Landau–Stuart equation. The governing equation is realized in a set of electronic circuits. When the target shows a limit cycle, by adjusting the coupling strength the state can be stabilized to a fixed point, and oppositely the target that is in a state of fixed point can be excited to a limit cycle. The results sufficiently agree with the theory and numerical calculations.
