The novel fuzzy sliding mode control problem is presented for a class of uncertain nonlinear systems. The Takagi-Sugeno (T-S) fuzzy model is employed to represent a class of complex uncertain nonlinear system. A virtual state feedback technology is proposed to design the sliding mode plane. Based on Lyapunov stability theory, sufficient conditions for design of the fuzzy sliding model control are...
Transdermal drug delivery system has an incomparable superiority to traditional medication systems, but its application was limited owing to low skin permeability. Aimed at the present situation, this paper analyzed the characters of dose-pulse based on the principle of transdermal drug delivery. Then several high accurate pulse waves and their combination are regenerated based on the theory of eleetroporation,...
An empirical analysis of the login information of fitness club membership in foreground system is implemented, which show that the interval time distribution of their logins present obvious Power-law properties whether all members, groups or individuals. Moreover, the scaling indexes of groups are different and linked with their level of activity. In addition, power exponents are obvious different...
Studies on human behavior not only contribute to a profound understanding of the complexity of socio-economic system and human beings, but also have broad prospects in practice. On the one hand, modeling of human behavior are essential for large-scale models of social organization, such as virtual urban models, modeling the spread of rumors or capturing financial market behavior etc; on the other...
A secure communication method via chaotic parameter modulation is studied. Based on Lyapunov stability theory and active control strategy, the simple controller is presented. Via chaotic parameter modulation, chaotic secure communication is derived. The particle filtering technique is designed in the receiving terminal to make the information signals recover effectively. The simulation results show...
Synchronization of unified chaotic systems and its application to secure communication are discussed. An adaptive control strategy for synchronization of unified chaotic systems in the present of uncertain parameter and external disturbances is presented, which can lead to achieve quickly synchronization between the drive chaotic system and the response chaotic system. After transformation of the...
A new discrete sliding mode control approach for parallel robot is presented to achieve accurate servo tracking in the presence of load variations, parameter variations and nonlinear dynamic interactions. A procedure based on predictive error is proposed to improve the traditional reaching law, which can guarantee the desired properties. The simulation results show that the proposed approach can improve...
