Hybrid position/force control is used to control both position and force of a multi-degree-of-freedom robot, which assigns position and force controls to different axes of the robot. Impedance control is an intermediate control of position control and force control, and hybrid impedance control is also used, which combines the hybrid position/force control and impedance control. The hybrid controls can achieve multiple control objectives with multiple-degree-of-freedom but cannot achieve multiple control objectives at a single-axis. This paper proposes periodic/aperiodic hybrid position/impedance control, where position and force are separated into periodic position, periodic force, aperiodic position, and aperiodic force with a periodic/aperiodic separation filter (PASF). The periodic/aperiodic hybrid position/impedance control assigns position and impedance controls to periodic motion and aperiodic motion at each axis of a robot. Accordingly, the proposed hybrid control achieves periodic and aperiodic control objectives at a single axis. To verify the effectiveness of the proposed hybrid control, we conducted the comparative experiments of the proposed periodic/aperiodic hybrid position/impedance control with conventional hybrid position/impedance control.","PeriodicalId":373423,"journal":{"name":"2021 IEEE International Conference on Mechatronics (ICM)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128087558","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 vibration suppression problem in flexible beams using a piezoelectric actuator as the actuator is discussed as a primary investigation. In the design support system, vibration response is calculated based on the elastic deformation obtained by finite element analysis on the computer. Particle swarm optimization is adopted to search the optimal actuator position based on the evaluation function. The parameters of the controller are determined by the nonlinear optimization for the frequency response of the plant calculated by finite element analysis.

Intersections especially unsignalized intersections are main regions occurring traffic accidents. Major part of reason is that drivers can not follow direction indicated by the traffic lights, that is to say, which drivers cannot know traffic lights in advance. And the interaction between traditional vehicles and signal lights mainly depends on eyes of drivers, but the influence of weather, front large truck, signal lamp malfunction and other external factors may cause some interference under the process of the information exchange. Owing to this problem, the authors propose a kind of self-controlled in-vehicle traffic light based on the 4th Generation mobile communication technology(4G) with Raspberry Pi 4B, SIM7600X-4G-HAT, GPS+BD double mode positioning module, 6 channel 5V low level trigger relay, model 300 road lift traffic lights and Android phones. Through the MQTT server, phones as the vehicle terminals interact with traffic lights to accomplish in-vehicle traffic lights. Traffic lights adjust their timing adaptively according to numbers of vehicles within 240s to ease the traffic pressure, which utilizes identification code of Universally Unique Identifier(UUID). Furthermore, broadcasting alert between Android phones is the beginning of information exchange among vehicles. The application is running in the background under the leisure time.","PeriodicalId":373423,"journal":{"name":"2021 IEEE International Conference on Mechatronics (ICM)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117284753","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}

An octonion-valued neural network with a feedforward network topology is considered and is applied to the design of a control system for handling dynamic control problems of a robot manipulator. In the control system, the output of the octonion-valued neural network is used as the control input for the robot manipulator to ensure that the end-effector of the robot manipulator tracks a desired trajectory in a three-dimensional space.

In general, it has not been easy to separate linear and nonlinear characteristics because measurement data includes both of the characteristics. However, it is possible to separate by assuming a model of nonlinear characteristics, searching for parameters of the nonlinear model, and estimating transfer function from the Frequency Response Data (FRD) without the effect of the nonlinearity. We call this method hybrid identification of time-series data and frequency data since FRD is used to estimate the linear transfer function, and time-series data is used to estimate the parameters of nonlinear characteristics. Moreover, Bayesian optimization is used as an efficient search method of the parameters of the nonlinear model. The effectiveness of the proposed identification method is verified by ball screw and rolling friction.","PeriodicalId":373423,"journal":{"name":"2021 IEEE International Conference on Mechatronics (ICM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114602212","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}
