CONTINUOUS FINITE TIME OBSERVER FOR CHAOTIC SYNCHRONIZATION
IFAC Proceedings Volumes, 2006 Abstract This paper introduces a new type of finite time observer for the synchronization of chaotic systems that can be put in Brunovsky canonical form up to output injection. The main contribution is that finite time observation is obtained using continuous output injections. The method is applied on the Chua's circuit.

Study of Head-Pursuit Cooperative Guidance Law for Near-space Hypersonic Interceptor
Journal of Aerospace Technology and Management, 2023 In order to intercept hypersonic vehicles in near-space, a head-pursuit cooperative guidance law is proposed in this paper. Firstly, interceptors are regarded as multi-agents, and the communication relationship between them is represented by graph ...
