Water of oil paper insulation in transformer will accelerate its insulation ageing, which is the key factor for its failures. Therefore, it is necessary to estimate water content of solid insulation for guaranteeing a safety and reliable operation of power transformers. The microstructure of insulation molecules can be varied by water, which affects the conductivity and polarization properties. Return...
Under the deregulation of generation market, all distributed generators will participate in electric power bidding; therefore purchase cost problem has been getting more attention of power companies. However, under the competition principle, they can purchase energy from several of power generation companies, so there exist continuous and integral variables in purchase cost model. It is difficult...
The problems of robust stability and stabilization for uncertain discrete-time singular Markovian jumpsystem is addressed in this paper. Firstly, a necessary and suffcient condition for a discrete-time singular Markovian jump system(MJL) to be stochastically admissible is proposed in terms of a strict linear matrix inequality(LMI). On the basis of this, the concepts of generalized quadratic stochastical...
The problem of the non-fragile dissipative control for the nonlinear discrete systems is dealt with. The T-S models is constructed for nonlinear systems, which makes the model approach to the original system more exact. The sufficient conditions for the existence of a dynamic output feedback fuzzy controller such that, for all admissible multiplicative controller gain variations, the closed-loop system...
