Provided in the present invention are a construction method for a hyperchaotic Lorenz system of different variables and facilitating ultimate boundary estimation and a circuit. Operational amplifier U1, operational amplifier U2, a resistor, and a capacitor are utilized to implement addition and integration operations. Operational amplifier U3 and a resistor are utilized to implement an inverting operation. Multiplier U4 and multiplier U5 implement multiplication operations in the system. Operational amplifier U1 is connected to operational amplifier U2, operational amplifier U3, and multiplier U5. Operational amplifier U2 is connected to operational amplifier U3 and multiplier U4. Operational amplifiers U1, U2, and U3 employ LF347BN. Multipliers U4 and U5 employ AD633JN. The present invention designs, on the basis of a chaotic Lorenz system, the construction method for the hyperchaotic Lorenz system of different variables and facilitating ultimate boundary estimation and a circuit construction method, also designs one analog circuit for implementing this chaotic system, and provides chaotic synchronization and control with a novel hyperchaotic system signal source. |
