Lu chaotic signal generator

The invention provides a Lu chaotic signal generator. The Lu chaotic signal generator is based on a Lu system, and comprises an X signal generation module, a Y signal generation module and a Z signal generation module which are inside the Lu chaotic signal generator, wherein the X signal generation module comprises a subtracter and a reverse phase integrator; the Y signal generator module comprises a phase reverser, a multiplier and a reverse phase integral adder; and the Z signal generation module comprises a multiplier and a reverse phase integral adder. The Lu chaotic signal generator has the advantages that parameters can be adjusted independently, the signal generator is convenient to use, programming is not needed, the process is simple, a single chip is not needed, and costs are low.
