Starting from a state-of-the-art discontinuous voltage droop control, which is used in point-to-point links, a continuously differentiable control function is developed. Using a mathematical description, the control function is transformed to meet the HVDC voltage control strategy for meshed HVDC grids. The control function's stability is discussed and its robustness is shown on an example. The example discusses and compares the current and future characteristics of the underlying AC transmission grid and the impact renewable in-feed has to the control function.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134594539","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}

Once the control signal exceeds the damper limitation, instability of the closed loop may occur. To ensure that the control signal is kept within the saturation range, an anti-windup controller is designed to maintain the closed loop stability of a robust optimal feedback controller. A Non-Model based Adaptive Controller (NMAC) is used together with the optimal feedback controller to cope with system uncertainties and nonlinearities. The proposed approach is applied to a quarter-car model with a semi-active damper, where nonlinear spring stiffness and nonlinear damper saturation are adopted. Simulation and experimental results have shown a significant improvement regarding the control performance.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124676559","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 robot is intended to provide physical support and mobility aid for the old people during their walking based on recognizing their motion intentions online. A force measuring system comprised of force sensing resisters (FSRs) is designed to obtain the interaction forces between the user and the robot. The user's motion intention is then estimated by analyzing the relationship between the measured interaction forces and human intention force/torque. Further the estimated intention is used to guide the admittance based motion control of robot. To ensure a safe walking, a laser range finder (LRF) is used to detect the distance between the robot and the user's legs. A distance restraint control is also designed and taken into action when the distance is found beyond a safe threshold. Experiments were conducted and the results verified the effectiveness of the developed robot system and control methods.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127532138","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, it is common that servomechanisms suffer from plant uncertainties and external disturbances which will affect the positioning accuracy. As such, this paper studies a robust control method called fast non-singular terminal sliding mode (FNTSM) control for a class of DSA systems. Compared with conventional sliding mode control, the FNTSM control can guarantee a faster convergence rate of the tracking error in the presence of system uncertainties including payload variations and external disturbances. Furthermore, it has the inherent feature of chattering-free in the control input. We also discuss the selection criteria of the controller parameters and then the FNTSM control method is applied to design the two control inputs of the DSA system. Simulations are studied to verify that the FNTSM controller can offer robust performance with respect to the mass variations and disturbance. Tracking performance achieved by conventional linear controllers is also presented for comparison.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"321 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116819918","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}

Under power and communication constraint, we seek a desirable tradeoff between communication rate and estimation performance in terms of estimation error covariance. We propose two data-driven sensor scheduling strategies to achieve that goal. We prove that under our strategies the minimum mean squared error (MMSE) estimator is a Kalmanlike filter which maintains linearity. We give the explicit MMSE estimator under each strategy.

This method utilizes the parallel characteristics of differential evolution (DE) and the high accuracy of Chebyshev polynomial interpolation to generate one side of the boundary of the reachable area, while conventional methods only generate one point of the boundary in each run. Furthermore, in order to assess the influence of the vehicle's design parameters on the maneuver capacity, a scoring method with analytic hierarchy process (AHP), which can greatly reduce the evaluation effort, is developed.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116280297","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}

As micro-blog posts' properties on short texts, together with their linguistic unreliable features and the incompleteness of lexical, it is necessary to analyze and cluster these similar posts together for the further data mining and recommendation. This paper takes advantage of the classical clustering algorithm of k-means, and then presents a novel modelling approach to partition the big data into the corresponding k groups. Furthermore, a text feature selection model based on 2-phase iteration is proposed. Based on this model, a micro-blog post clustering algorithm is present.

The variation in the modal dynamics may cause degradation in performance. This paper presents an adaptive positive position feedback method for controlling the vibration of a flexible beam with bonded piezoelectric sensors and actuators. Dynamics of an experimental flexible beam is modeled via finite element method. The proposed vibration controller combines the positive position feedback (PPF) with an online adaptive parameter estimator based on the gradient algorithm with parameter projection and a dead zone. Since the online estimator is able to identify the modal frequencies, the PPF controller is able to damp out the target modes quickly. Simulation results are presented to illustrate the effectiveness of the proposed control method.","PeriodicalId":405363,"journal":{"name":"Proceedings of 2014 International Conference on Modelling, Identification & Control","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126730370","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}
