Internet of things has be broadly applied for home, industry, and many other applications. For these applications, secure information transmission becomes a critical issue to ensure the system safety. Hybrid encryption technique is a new cryptographic paradigm and it can be applied to the Internet of Things. It provides the benefit of the symmetric key and asymmetric key performance. It enables strong...
In this paper, an adaptive backstepping sliding mode control approach is proposed to attenuate the tracking error and control the MEMS triaxial gyroscope. An adaptive backstepping controller that can compensate the system nonlinearities is incorporated into the sliding mode control scheme in the Lyapunov framework. First, a robust backstepping control system incorporated with sliding mode control...
In order to deal with the nonlinearity terms and parameter uncertainties and external disturbances of MEMS triaxial gyroscope, an adaptive fuzzy sliding mode control strategy, which combines the merits of sliding mode control and the indirect adaptive fuzzy control, is proposed to control the position of MEMS gyroscope in the presence of model uncertainties and external disturbances. The adaptive...
For the tracking control problem of vehicle suspension system, a method of adaptive sliding mode control is derive in this paper. The influence of parameter uncertainties and external disturbances on the system performance can be reduced and control robustness can be improved. The adaptive sliding mode controller is designed so that the practical system can track the state of the reference model....
To detect amplitude-frequency characteristics of filter with single or differential port is introduced. A novel instrument to detect amplitude-frequency characteristics of xDSL filter is designed considering the specific detection requirement, which applies with multiple modern technologies of MCU, DDS, LPF, auto control and high-frequency small-signal amplification. The verifying experiment contrasted...
