In order to solve this problem, an automatic frequency tracking system based on FPGA is developed. The system makes use of fast Fourier transform (FFT) combined with fuzzy proportional-integral-derivative (PID) algorithm. Then, a frequency-tracking strategy is proposed to catch the optimal working frequency. The upper computer software is used to control and monitor the whole system, which is more convenient for various application scenarios. It is proven that the tracking of resonant frequency of the ultrasonic transducer can be achieved quickly and accurately. Furthermore, the main advantage of the design system is miniature, versatility and high stability. Finally, the effectiveness of proposed system is validated by an experimental example.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129636584","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}

Firstly, the degree of freedom is analyzed based on screw theory. Secondly, kinematic analysis is conducted for the varied-width straight-line mode to obtain the velocity Jacobian matrix. Stiffness analysis is conducted based on the velocity Jacobian matrix to obtain the stiffness performance under different widths of straight-line mode. Finally, the ratio of the instantaneous motion power at the output of the mechanism to the instantaneous input power at the input is used as the evaluation index of the mechanism motion/force transmission efficiency. The motion/force transmission efficiency is analyzed in the variable width mode, and the transmission efficiency in the straight line mode with different widths is obtained. By comparing the stiffness performance and the motion/force transfer efficiency of the straight mode with different widths, it can be concluded that the mechanism has the best performance in mode d, with high bearing capacity and moving capacity.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116185415","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}

Displacement excitation is applied to X-axis and Y-axis to form ultrasonic elliptical vibration cutting (UEVC). The influence of tool parameters such as rake angle and clearance angle on cutting force and cutting temperature is studied by single factor method in this process. The results show that when the rake angle of the tool exceeds 32°, the cutting force and temperature of the tool increase sharply, which has a essential impact on the service life of the tool. Therefore, it is vital to control the rake angle of the tool less than 32° for prolonging the service life of the tool when turning titanium alloy. The cutting force and the cutting temperature increase with the increase of tool rake angle and decrease with the increase of tool clearance angle. The results provide a reference for choosing the geometric angles of the tool for ultrasonic elliptical vibration turning of titanium alloy.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123818737","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 model, we presents a controller for regulating the lateral rolling angle of the bicycle robot by using Global Terminal Sliding Mode Control methodology.

It requires us to allocate the car spacing according to the environment in which the vehicle is traveling, and improve the utilization of the road under the premise of ensuring driving safety. The fixed-pitch spacing strategy is not suitable for complex driving environments, while the variable spacing strategy has certain disadvantages in terms of stability and security. This paper combines the advantages of nonlinear spacing strategy, improves the VTH strategy based on the previous studies, and verifies the convergence of the improved model through mathematical analysis. Finally, the simulation models were built in matlab environment, and the five classics folowing-control states of ACC were simulated.

The parking algorithm is usually decomposed into two parts: path planning with geometrical method and path following. Actually, many papers have contributed on improving the performance of automatic parking algorithm. Among the existing algorithms, the jerks of curvature at some reference path points are hard to be avoided. The problem increases the difficulty of tracking. In path tracking, the simple proportion-integration-differential(PID) controller can not meet the requirements on high precision and stability. Therefore, this paper aims at generating smooth trajectories and tracking them precisely and stably. Firstly, the proposed algorithm utilizes circular arcs to obtain initial reference parking paths in view of passable constraints like slots' boundaries and road boundaries. Secondly, the algorithm chooses appropriate Bezier curves to ease the jerks at path joints. Finally, the controller based on model predictive control(MPC) is designed for path tracking. The automatic parking algorithm is verified in MATLAB and vehicle dynamics simulation software PreScan. Simulation results show that the proposed algorithm is feasible and efficient.","PeriodicalId":105852,"journal":{"name":"Proceedings of the 2019 International Conference on Robotics, Intelligent Control and Artificial Intelligence","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127614582","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 dynamics model of the mechanism is established and simulated, and the kinematic property of the mechanism under three different operating modes is analyzed. The results show that the deformation and torque of the torsion spring at the singular configuration are the largest when the mechanism moves between the left and right limit blocks, and the fast switching phenomenon occurs when the mechanism reaches the singular configuration. It only takes the mechanism 0.33s to move from the singular configuration to one limit position.
