The invention provides a chen chaotic system switching method and circuit containing y<2> with different fractional orders. An operational amplifier U1, an operational amplifier U2, a resistor and a capacitor are utilized for forming an inverting adder and an inverting integrator with different fractional orders. A multiplier U3 and a multiplier U4 are utilized for achieving multiplication, and an analog switch U5 is utilized for achieving selective output of analog signals. LF347Ds are adopted as the operational amplifier U1 and the operational amplifier U2. AD633JNs are adopted as the multiplier U3 and the multiplier U4, and an ADG888 is adopted as the analog switch U5. The operational amplifier U1 is connected with the multiplier U3, the multiplier U4 and the analog switch U5, the operational amplifier U2 is connected with the multiplier U3 and the analog switch U5, the multiplier U3 is connected with the operational amplifier U1, the multiplier U4 is connected with the operational amplifier U2, and the analog switch U5 is connected with the operational amplifier U1 and the operational amplifier U2. The novel chaotic system switching method and circuit provide a new thought for adding chaotic system switching types and facilitating application of the chaotic system to engineering practice.
