24. A Novel Disturbance Observer Based Fixed-Time Sliding Mode Control for Robotic Manipulators with Global Fast Convergence

Author

Zhang, Dan, Hu, Jiabin, Cheng, Jun, Wu, Zheng-Guang, and Yan, Huaicheng

Abstract

This paper proposes a new global fixed-time sliding mode control strategy for the trajectory tracking control of uncertain robotic manipulators. First, a fixed-time disturbance observer (FTDO) is designed to deal with the adverse effects of model uncertainties and external disturbances in the manipulator systems. Then an adaptive scheme is used and the adaptive FTDO (AFTDO) is developed, so that the priori knowledge of the lumped disturbance is not required. Further, a new non-singular fast terminal sliding mode (NFTSM) surface is designed by using an arctan function, which helps to overcome the singularity problem and enhance the robustness of the system. Based on the estimation of the lumped disturbance by the AFTDO, a fixed-time non-singular fast terminal sliding mode controller (FTNFTSMC) is developed to guarantee the trajectory tracking errors converge to zero within a fixed time. The settling time is independent of the initial state of the system. In addition, the stability of the AFTDO and FTNFTSMC is strictly proved by using Lyapunov method. Finally, the fixed-time NFESM (FTNFTSM) algorithm is validated on a 2-link manipulator and comparisons with other existing sliding mode controllers (SMCs) are performed. The comparative results confirm that the FTNFTSMC has superior control performance.

Abstract

The thermoelectric (TE) technology can harvest the waste heat to generate electrical energy. However, TE parameters decoupling is a big challenge to optimise the performance. Herein, we fabricated the Cu1.75Te nanowires (NWs) based bulk materials by spark plasma sintering of the solvothermal synthesised Cu1.75Te NWs towards decouple the thermal and electric performances. The results indicate that the ultrathin Cu1.75Te NWs with the diameter of ~10 nm can be synthesised, which serve as building blocks for fabricating bulk TE materials with nanonetwork structure inside the bulk. This unique nanonetwork structure plays a vital role in decoupling TE parameters. Its peak zT reaches 0.09, higher than the counterparts of reported Cu2Te bulk and Cu1.75Te nanosheets based bulk. Thus, building Cu1.75Te NWs based bulk materials is thought to be an effective way to decouple the TE parameters. [ABSTRACT FROM AUTHOR]

Abstract

The S-transform is an efficient tool for time-frequency analysis that gained interest in many signal processingapplication fields. This is due to its ability to produce an analysis with a frequency dependent resolution, as for the wavelettransform, while keeping a direct relation with the Short-Time Fourier Transform (STFT). In this paper, the S-transform is firstbriefly recalled with its properties and its relationships with the STFT and the Continuous Wavelet Transform (CWT). Then, wepropose to enhance the S-transform using the reassignment and the synchrosqueezing methods, which have been already successfullyapplied to the STFT and the CWT. Thanks to these methods, we provide a “sharpen” time-frequency representation from theS-transform while allowing a signal reconstruction thanks to the synchrosqueezing method. The Levenberg-Marquardt algorithmis also used to provide reassignment and synchrosqueezing operators for the S-transform that allow a user to adjust thestrength of the resulting time-frequency distribution. We also derive for the S-transform a second-order synchrosqueezingoperator that improves the time-frequency localization of the synchrosqueezed S-transform by considering signals with frequency-modulatedcomponents. Finally, numerical results obtained with the reassigned and synchrosqueezed S-transforms are comparedwith the Gabor STFT and the Morlet CWT.

Abstract

As the development of the intelligent transport system, motor vehicle electrical identification system, based on the theory of radio frequency identification, is widely researched to strength the traffic management. The motor vehicle electrical identification system is mainly composed of the tag, the reader and other aspects. Usually, the vehicle information, including the license number, the traveler name, the identification number and other personal information, is stored in the tag. Considering the radio communication between the tag and the reader, the personal security may be destroyed if the vehicle information is leaked. Therefore, this paper introduces a new process about reading and writing the tag of motor vehicle electrical identification system. Firstly, it designed the structure about the storage of the tag, including the information security area, the controlling area and the information area. Then, it proposed the method about reading and writing each area. Experimental results show that the proposed method can satisfy the command needing of the traffic management.
