Description

technical field [0001] The invention relates to the technical field of chaos control, in particular to a method for synchronous control of an uncertain time-delay chaos system. Background technique [0002] Chaos is an important form of motion in nonlinear systems. Chaos phenomena exist widely in social life. Because of its high sensitivity to initial values ​​and unpredictability, the study of chaotic systems is very important. The research on the chaotic system also fully embodies the idea of ​​two sides of things. When chaos is beneficial, we use scientific methods to strengthen its chaotic effect to serve us better, such as using the chaotic phenomenon in astrodynamics to design aerospace The trajectory of the device can be used to reduce fuel consumption; the principle of chaos can be used to improve the mixing efficiency of fluids with different densities; the principle of chaos mechanics can be used to improve the treatment of Parkinson's and other diseases. For harm...
