The unknown functions caused by the different passenger masses and uncertain factors are estimated by neural networks. To guarantee the chassis displacement within limited constraints, the prescribed performance function is used to describe the convergence rate of tracking error and ensure the maximum overshoot within the boundaries. The vertical displacement and pitch angle of the half-car model are considered simultaneously to improve the riding comfortability and handling stability of suspension performance. The comparative simulation examples will be realized to show the feasibility and effectiveness of the developed method.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125511717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The RBF -based function approximators are employed to deal with unstructured uncertainties, whereas UDE-based disturbance observers are designed to estimate not only lumped mismatched disturbance but also matched disturbance. The derivatives of system states are obtained by using high-order Levant's exact differentiators. Finally, the adaptive robust control law is synthesized to attenuate the imperfections in disturbance estimation and NN-based approximation performances and guarantee high-accuracy tracking performance. The stability of the closed-loop system is analyzed by using Lyapunov theory. Comparative simulations based on an electro-hydraulic rotary are conducted using MATLAB/Simulink to verify the effectiveness of the proposed control approach.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116716735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Destructive material testing is the common method to determine Young's modulus. This paper presents the vibration measurement technique using Digital Image Correlation (DIC) as an alternative method to determine the Young's modulus of materials. The principle is based on the linear transverse vibrations of a Euler-Bernoulli cantilever beam with clamped-free boundary conditions. The dynamic responses of three materials (steel, aluminium and brass) were discussed. For each material, the beam was subjected to an initial static transverse displacement at its free end and then allowed to vibrate freely. The vibrations at the free end were captured using DIC measurements, and the results processed and presented in the form of displacement versus time, following which the natural frequencies of the beam can be obtained using the method of Fast Fourier Transform (FFT). The Young's modulus can then be derived using the first natural frequency and the geometry of the beam. The calculated Young's modulus values obtained using the DIC measurements of the free vibrations are compared with the modulus obtained using the static deflection approach, which shows highly favorable agreement. The use of the vibration method to determine Young's modulus using DIC method can help in the non-contact assessment of the existing structural integrity without subjecting test specimens to destructive testing.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116226697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The examined parameters included the pressure ratio of the air compressor $(mathbf{r}_{mathbf{p}})$, the gas turbine inlet temperature, the steam turbine inlet pressure and the condenser pressure to evaluate thermal performance, exergy performance, and total annual cost (TAC). The mathematical model was established and solved in the environment of Engineering Equation Solver (EES) with comparison of results from the Aspen HYSYS simulator. The calculation results show that the exergy efficiency is maximum at $mathbf{r}_{mathrm{p}}=mathbf{11}$. TAC is strongly influenced by gas cycle operating parameters. The minimum TAC can obtain at the steam turbine inlet pressure of 5,300 kPa. Overall optimization reveals maximum efficiencies and minimum cost at pressure ratio of 8.65, gas turbine inlet temperature of 1460 K, the smallest condenser pressure, and the highest steam turbine inlet pressure.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129364097","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, proper energy and power management are some of the critical issues for fuel cell-based energy storage system (ESS) because the degradation of a fuel cell lifetime is strongly affected by its operating condition. In this paper, a modified-optimal energy management strategy (MOEMS) is proposed which determines the power-split ratio between the FC and battery efficiently. By integrating the popular gradient-descent algorithm into a state machine control the proposed controller is realized. The performance of the MOEMS is compared with conventional EMS with simulation. Results suggest that the proposed EMS improve the fuel cell lifetime by 44% while reducing the fuel consumption by 7% compared to the basic EMSs.","PeriodicalId":258783,"journal":{"name":"2021 24th International Conference on Mechatronics Technology (ICMT)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127304947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the move towards a digitized world, it is necessary for the healthcare sector to adopt appropriate responses to the changing needs. Upper limb rehabilitation services are one such unit of the healthcare sector that can benefit from modern technologies and solutions. We have proposed a system called “Therapy Easy” which is a flexible therapy system to carry out rehabilitation at the comfort of the user.

The static characteristics of the negative stiffness elements as well as the nonlinear mathematical model are presented.

This study presents the evaluation of battery degradation through different smart charge strategies and vehicle-to-grid scenarios. The simulation results show that the developed smart charge schemes can mitigate the battery ageing up to 5% while lowering the charge cost from 30 - 60% as comparing to the conventional charge method within the first five days operation of the battery.
