Robust stabilization of a class of time-delay nonlinear systems with Markovian jump

The problem of robust stabilization of time-delay nonlinear systems with Markovian jump with a triangular structure is studied. Based on backstepping method, we prove that the closed system is almost surely asymptotically stable and the controller and the associated Lyapunov function is independent of the generator of the Markov process.

A routing method based on wireless sensor network for smart meter reading system

Smart meter reading system is the core of advanced metering infrastructure for Smart Grid. Wireless sensor network is an important means to realize the power information collection. Based on hierarchical strategy, this article proposed a method to establish routing in wireless smart meter reading system. This method provides reliable two-way communication routing, but also greatly reduces the collision probability of network communications. In order to verify the feasibility of the approach, a large number of simulation experiments were carried out. This idea has been applied in actual engineering practice.
