The slow movement causes rare pulses generated from the encoder, rarer than the sampling frequency. In such conditions, the velocity calculation by numeric derivative or Luenbergera observer fails. For that, it is proposed a new velocity estimation algorithm that uses information specific for encoder operating mode. Simulation and real-time experiments have shown a significant reduction in velocity error estimation of the proposed algorithm in comparison to conventional algorithms.","PeriodicalId":189753,"journal":{"name":"2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127014401","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 the paper, interactions between agents are defined like in Cucker-Smale models, where equations related to the position are the ordinary differential equations and velocities of agents are described by fractional differential equations. It allows us to take into account the memory that is included by taking the fractional-order, what seems to significantly improve the classical model. The conditions for achieving the consensus for the considered models are formulated based on the stability analysis of the appropriate linear systems. Finally, the behaviours of systems are illustrated by examples.","PeriodicalId":189753,"journal":{"name":"2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125208253","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}

It is a variant of the Continuous Knapsack Problem in which no more than a specified number of variables are allowed to have positive values. This problem arises when a limited resource is allocated among competing activities, and an upper bound is imposed on the number of activities that can be selected in a solution. The Cardinality Constrained Knapsack Problem is NP-hard. We analyze the structural properties of its optimal solutions and propose procedure allowing to reduce the size of the original problem.","PeriodicalId":189753,"journal":{"name":"2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124674432","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}

MC is becoming widely used because of the unity power factor and the lack of energy storage element. FOC method calculates the duty of MC states with use of geometric relations between voltage and current vectors. DTC method, on the other hand, is based on controlling the length and angle of a stator flux linkage vector with MC states chosen from a Switching Table. Simulation research of control algorithms was performed in MATLAB/Simulink 2013b. Authors compared the quality of moment regulation in both methods, including the electromagnetic torque rise time and torque variance. Moreover, influence of a control algorithm on the power grid current was researched in frequency domain by FFT and THD. DTC method for MC proved to be faster in torque control. FOC method, however, has visibly lower torque ripples and lower THD. Both methods performed well in a torque regulation of a MC fed motor.","PeriodicalId":189753,"journal":{"name":"2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129873230","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 reason, a recently introduced polynomial matrix σ-inverse is applied to LTI nonsquare systems described by discrete-time state-space framework. It is shown that classical minimum-norm right inverse is not sufficient to obtain the minimum-energy of control runs. Thus, the σ-inverse with parameter/polynomial, so-called degrees of freedom, gives better results than typical Moore-Penrose inverse in terms of said lower energy. The effectiveness of the presented method is confirmed by simulation examples in Matlab environment.","PeriodicalId":189753,"journal":{"name":"2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133733059","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}

Classically, such control strategies make use of the actuation of a crane trolley to counteract the motion of a swinging payload. As an alternative to controlling trolley motions, variations of the rope length can be considered. In contrast to scenarios where trolley motions are used to attenuate oscillations, the control of the rope length is a more challenging task due to non-negligible nonlinearities and due to the presence of points in the state-space for which controllability is not guaranteed. In this paper, a novel extended linearization approach is presented for the oscillation attenuation in crane systems, where the feedback gains are determined by using a robust optimization procedure which employs a formulation of the control task in terms of linear matrix inequalities. Simulation results and an experimental validation highlight the practical applicability of the proposed control procedure.","PeriodicalId":189753,"journal":{"name":"2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132219053","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}
