   Analysis and Diagnosis on Open-circuit Fault of Diode Rectifier in 12-phase Synchronous Generator System
By Ziguo HUANG, Yuguang SUN, Shanming WANG, Xiwen YU [View]
[Download]

Abstract: This paper deals with a 12-phase synchronous generator with open-circuit fault of diode rectifier. Considering all space harmonics of air-gap magnetic field and the changing circuit topology, the mathematical model of the system is established based on the multiloop theory of machine. A series of experiments have been conducted on a 4-kW 12-phase synchronous model machine. The acceptable agreement between the simulated and experimental result validates the modeling process. Based on the analysis, the features of the open-circuit fault of rectifier are summarized. Finally, the algorithm of DC voltage odd harmonic detection is raised.

   Classification and Compensation of Amplitude Imbalance and Imperfect Quadrature in Resolver Signals
By Jong-Joo MOON, Hong-Jun HEO, Won-Sang IM, Jang-Mok KIM [View]
[Download]

Abstract: This paper proposes a detection and compensation algorithm of two non-ideal output signals of a resolver to reduce position error. Practically, a resolver generates position errors because of the amplitude imbalance and imperfect quadrature between the two output signals of the resolver. In this paper, a digital signal processor (DSP) based resolver-to-digital converter (RDC) is used to reconstruct the two output signals of the resolver. The proposed algorithm does not need any additional hardware. Furthermore, this algorithm can be applied to both the steady and transient states. The simulation results verify the effectiveness of the proposed algorithm.

   Dynamic Magnetic Circuit Modelling of Permanent Magnet Linear Motor
By Marko HUIKURI, Niko NEVARANTA, Juha PYRHÖNEN, Markku NIEMELÄ [View]
[Download]

Abstract: Usage of a magnetic circuit model as part of a dynamic simulation model of a non-salient permanent-magnet linear synchronous motor drive is investigated. The complete dynamic system model includes position control, motor magnetic circuit and mechanical models. A dynamic motion profile is simulated to demonstrate the dynamical capability of the simulation method proposed. To validate the simulation results measurements have been done with a linear drive, including a commercial permanent magnet linear motor. The same motion profile as in the simulation has been used. The experimental results show a good correlation with the simulation results. The correlation is high both in the system model level and in the motor model level showing e.g. the saturation effects during operation points with high force demand.

   Dynamic Performance of Mechanical-level Hardware-In-the-Loop Simulation
By Tuomo LINDH, Jan-Henri MONTONEN, Jarkko NOKKA, Juha PYRHÖNEN, Lasse LAURILA, Markku NIEMELÄ [View]
[Download]

Abstract: This paper discusses dynamic behavior, stability and performance issues of the mechanical-level hardware-in-the-loop (MHIL) simulation. A special interest is in the cases where a real-time multi-body mechanics simulator is used to produce load dynamics to HIL hardware. The transfer functions describing the HIL system dynamics are created and presented. The analysis using transfer functions, the simulation results and test results using actual MHIL simulation are presented. The analysis shows that the performance and stability of the device under test cannot be concluded without case by case analysis of HIL-setup as a whole.

   GENERAL COMPARISON OF DIRECT AND GEARED DRIVES FOR CONTROL APPLICATIONS

Abstract: This paper considers basic criteria which should be taken into account when an electric drive designer selects between geared (GD) and direct drives (DD).

   Robustness of Control Methods Based on Servomechanism Direct Speed and Speed Estimation for Controlling Residual Vibration
By David LINDR, Jan OPÁLKA [View]
[Download]

Abstract: This paper describes comparison of two previously published approaches for active damping of theservomechanism residual vibration; model based feedback control and direct output speed sensing andprocessing method. The benchmark of this comparison is an experimentally measured and evaluatedrobustness characteristic of both methods against the changes in residual vibration frequency andamplitude.
