Sliding mode control is introduced into classical model free fuzzy logic control for discrete time nonlinear systems with uncertainty to the design of a novel fuzzy sliding mode control to meet the requirement of necessary and sufficient reaching conditions of sliding mode control. The simulation results show that the proposed controller outperforms the(More)
A novel sliding mode controller based on Takagi-Sugeno fuzzy model is designed for a class of nonlinear systems to tackle the nonlinear control problems with modelling uncertainties, time varying parameter fluctuations and external disturbances. A numerical example is simulated to verify the performances of the proposed control strategy, and the simulation(More)
As the main revenue source of Internet companies, online advertising is always a significant topic, where click-through rate (CTR) prediction plays a central role. In online advertising systems, there are often many advertisement products. Due to the competition in the bidding mechanism, some advertising products may get lots of data to train the CTR(More)
