A new simple chaotic Lorenz-type system and its digital realization using a TFT touch-screen display embedded system
Summary: This paper presents a new three-dimensional autonomous chaotic system. The proposed system generates a chaotic attractor with the variation of two parameters. Analytical and numerical studies of the dynamic properties to generate chaos, for Continuous Version (CV) and Discretized Version (DV), and for the new chaotic system (NCS) are conducted. The CV of the NCS is implemented by using an electronic circuit with Operational Amplifiers (OAs). In addition, the presence of chaos for DV of the NCS is proved by using the analytical and numerical degradation tests; the time series is calculated to determine the behavior of Lyapunov Exponents (LEs). Finally, the DV of NCS is implemented, in real-time, by using a novel Embedded System (ES) Mikromedia Plus for PIC32MX7 that includes one microcontroller PIC32 and one thin film transistor touch-screen display (TFTTSD), together with external digital-to-analog converters (DACs).
