Synchronization for a class of chaotic systems
一类混沌系统的同步方法

A kind of receiver is constructed according to the character of transmitter. A feedback control used to synchronize this transmitter and the constructed receiver is proposed based on sliding mode control design. To make this controller physically realizable, an extended state observer is used to estimate the difference between the transmitter and receiver. Numerical simulations are carried out to show the effectiveness of this design based on Duffing oscillator and Chua's circuit.
