FPGA CHIP WITH FUZZY PWM CONTROL FOR SYNCHRONIZING A CHAOTIC SYSTEM

A field-programmable gates array (FPGA) chip with proposed fuzzy pulse width modulator (FPWM) control for synchronizing master-slave chaotic systems with uncertainties is proposed in this paper. The proposed FPWM is constructed by DSP Builder tool which can be co-simulated with other Matlab/Simulink tool and can be directly converted to hardware description language to download into FPGA chip. Combine a master-slave chaotic plant constructed in Matlab platform with the proposed FPGA chip as a FPGA-in-loop configuration to show that the synchronizing precision is good enough by using our proposed FPGA chip control. Hardware experiment shows the feasibility of the proposed design scheme.
