LQR Chaos Synchronization for a Novel Memristor-Based Hyperchaotic Oscillator

In a three-dimensional dissipative chaotic system circuit, by superimposing cubic magnetron-type memristor and connecting feedback new four-dimensional synchronous controlling is established. The control parameters have significant impact on the system, displays rich dynamic features such as hyperchaos, chaos, period states. At same time, synchronization scheme for designed based linear quadratic regulator (LQR), which effectively improves response speed reduces complexity of system. Further, numerical verification carried out. Finally, detailed system’s characteristics performed hardware simulation. Simulation results performance analysis show that proposed method has performance. Compared to some existing schemes, this more widely applicable.
