For this type of tactile display, multiple actuators with small volume and weight are required with the capability of position and force feedback control. The position and force sensors are usually large in terms of the volume. Thus, in this paper, compact solenoid actuators are used with a sensorless position and force estimation technique, and the estimated position and force information are used in bilateral control for communication of haptic information between master and slave actuators. A bilateral experimental system with master/slave actuators was constructed, and the experimental results indicated that the position and force were communicated in the master/slave system. As a result it was confirmed that the bilateral control was realized without position and force sensors with a small volume and light weight experimental setup.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122501912","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}

Due to the nonholonomic kinematics model, it is difficult to drive flexible needles to track a pre-plan path. In this paper, we propose an effective path tracking control method based on Model Predictive Control (MPC). The kinematics model of flexible needles is described firstly, according to which the control method is designed. Then, the path tracking control method is presented in detail. The finite prediction horizon of MPC is extended to infinite in order to obtain a global optimal solution. Due to the nonlinear model, the objective function of receding horizon optimization is also nonlinear, and Particle Swarm Optimization (PSO) is employed to search optimal predictive control series. At last, simulations are conducted and results illustrate that the proposed controller performs well to precisely drive the flexible needle to track a desired path.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122960619","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}

Despite the fact that cities are more and more aware of the difficulties that wheelchair users have to deal with and despite their increasing concern to provide them a friendlier environment, the gap between non-disabled people and disabled people still exists. To improve their quality of live, enhancements can also be done on the wheelchair itself. For example, electric wheelchairs reduce the required physical effort to move. But one of the trickiest situations are steps. They are omnipresent in cities and even if their rise height is small, they are still an obstacle. In this paper, a control method combining computer vision environment detection and modern control theory is proposed to achieve step-passage motion with a two-wheel wheelchair.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"57 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116515449","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}

In this paper, the measurements of the estimation of the impedance at the end effector of the arm are performed based on frequency analysis. Two experiments of the active muscle condition and relaxed muscle condition of the arm are carried out on the three directions determined in accordance with the functionally effective muscle (FEM) theory that the output direction at the end effector of the arm is derived from the output of the specific muscle groups. These experiments indicate how much the arm can increase the stiffness of the each direction at the end effector of the arm on the FEM theory.

And some recent researches show that an adaptive controller that dynamically determines the master's controller gain depending on a stiffness of a contact object is effective to improve stability. However few researches show an influence of time-varying communication delay in adaptive controller based bilateral control systems. This paper therefore verifies an influence of time-varying communication delay. A PI (polynomial interpolation) with a schmitt trigger is utilized to estimate a stiffness of a contact object. Simulation results show that the PI based estimation method has a robustness against a constant/time-varying communication delay. An experiment of a bilateral control over an IP (Internet Protocol) network emulator also show the validity of the estimation method.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127103408","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, the human-machine cooperative control is still a key challenge in this domain. This paper presents a new approach for walking assist control that uses Inertial Measurement Units (IMUs) fixed on elderly people's body to track their posture and estimate its Center Of Mass (COM) and Zero-Moment Point (ZMP) motions to be used by a differential mobile robot that synchronize with the user's walking motion. Furthermore, a manipulator mounted on the mobile device to support the users from their back, help them walk, and assist in dangerous situations. In this study, the walking is divided into phases according to the falling index defined, and the impedance of the manipulator is changed based on the stability of the situation. Experiments of the walking assist control were carried out, and by their results the validity of the proposed approach is confirmed and the fall avoidance is realized.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125231281","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}

Since the proposed shaking table mechanism sets up each actuator in horizontal excitation direction on the side of the table, the movement of table requires the coordinated control of each actuator. In the proposed shaking table system, therefore, the references for each actuator are generated on the basis of the target table motion and geometric arrangement. In addition, zero phase error tracking algorithm as a feedforward compensator is applied to completely synchronize the motion of all actuators. The effectiveness of proposed shaking table mechanism and control system has been verified by numerical simulations using a horizontal shaken laboratory prototype.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"354 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134497912","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}

In this paper, a decoupling method utilizing a high-precision stage with multiple actuators is proposed. According to a model considering the misalignment between the center of gravity (CoG), the center of rotation (CoR), the actuation point, and the measurement point, the coupling characteristics from the translational force to the angle can be changed by varying the height of the actuation point. The model indicates that a CoR-driven method can suppress the coupling in the low frequency range and a CoG-driven method can suppress the coupling in the high frequency range. This paper proposes a CoR and CoG hybrid-driven method using complementary filters to place the actuation point at the CoR and the CoG in low and high frequency ranges, respectively. The effectiveness of the proposed method is verified by experiments.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115775115","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}
