摘要
从混沌保密通信的要求出发 ,根据驱动混沌系统特点 ,任意构造满足一定条件的响应系统 ,在滑模控制策略和扩张状态观测器基础上 ,得到物理可实现的控制策略以弥补驱动、响应系统结构的差异并实现二者的同步 ,在此基础上实现信息传输。通过对 Duffing和 Chua′s电路的仿真证明效果良好。
Based on the concept of chaotic secure communication, a kind of receiver is constructed according to the character of transmitter. Extended state observer is used to estimate the difference between transmitter and receiver. A physical realizable controller is proposed based on sliding model control and this estimated information to achieve synchronization between them. Numerical simulations show the effectiveness of this design based on Duffing oscillator and Chua's circuit.
