IPMSM motion-sensorless direct torque and flux control

IPMSM motion-sensorless direct torque and flux control

Annual Conference of Industrial Electronics Society

The paper presents a rather comprehensive implementation of a wide speed motion-sensorless control of IPMSM drives via direct torque and flux control (DTFC) with space vector modulation (SVM). Signal injection with only one D-module vector filter and phase-locked loop (PLL) observer is used at low speeds to estimate the rotor position and speed, to be used in the stator flux observer and, respectively, as speed feedback. A combined voltage-current model flux observer suits the whole speed range, while the current model fades away as speed increases. PWM and inverter nonlinearities compensation provides for a smooth current waveform even at 1 rpm. The paper demonstrates through ample experiments a 1750 rpm/1 rpm speed range full-loaded with sensorless DTFC-SVM.

New fast moving markets demand flexible, adaptable production facilities to allow manufacturing companies a fast reaction on consumer needs. Reconfigurable manufacturing systems provide a solution for these problems. Currently used software architectures have not been designed for providing an infrastructure for such manufacturing systems. With the new standard IEC 61499 the International Electrotechnical Commission provides an architecture for flexible distributed control systems. But it leaves open points regarding real-time execution and reconfiguration in realtime. This work focuses on real-time execution of IEC 61499 applications. It describes all execution elements of IEC 61499 within a device. Different implementation and scheduling approaches are compared and discussed. A first real-time scheduling approach for IEC 61499 control applications allows executing applications with periodic real-time constraints in parallel to unconstrained applications. It serves as a base for an enhanced full featured IEC 61499 real-time execution support.

Intelligent Space is a space which has ubiquitous distributed intelligent devices. The mobile robot in the space is called mobile agent. Mobile agent becomes more intelligent through interaction with the space and supports people effectively. For this purpose, objects in Intelligent Space have to be recognized and tracked. In this paper, moving object tracking system in Intelligent Space is described. In addition, a mobile robot which follows observed human walking path with support of Intelligent Space is also presented. © 2005 SICE.

The paper gives an overview of the Yoto project, a novel e-learning initiative to build up an electrical engineering knowledge base. It also presents a new e-module of the project relating to the steady-state operation of DC-DC converters. The multimedia rich module contains numerous interactive tools promoting the high level education in the academy sector and the vocational trainings in the industry. The interactive tools also highly support the circuit design process by enabling fast calculation and access to relevant circuit quantities and waveforms (voltages and currents) in steady-state without long simulations

Annual IEEE Conference on Power Electronics Specialists (PESC)

The nonlinear phenomena of direct torque controlled (DTC) induction machine (IM) is investigated. Since the system is strongly nonlinear due to the hysteresis comparators, various nonlinear phenomena are expected. The objective of the paper is the study of these behaviors, exploring various system states from regular periodic operations to chaotic ones. The main goal is twofold, first by obtaining a deeper insight into the operation of DTC-IM the design of control parameters (width of hysteresis loops) can be supported with the help of the techniques of nonlinear dynamics such as Poincare maps and Bifurcation diagrams, secondly the sudden changes of system states or bifurcations expected due to the nonlinearities can be detected and studied.

The paper is concerned with the design of the bang-bang control for dual channel DC-DC buck and boost converter. The quality of the control is characterized by two quality figures, the voltage ripple and the voltage error. An optimum design method is described to realize good quality figures. When the output voltage is higher (lower) than the reference voltage the lower (higher) switching frequency is selected. In order to reduce the output voltage ripple the lower switching frequency is changed with the variation of the load. Calculation and simulation results of the two quality figures are presented and compared.

A Novel Adaptive Control System for Raw Material Blending

引用

IEEE Control Systems 2003年第1期23卷 87-96页

作者： Banyasz, Cs Keviczky, L. Vajk, Istvan Computer and Automation Research Institute Hungarian Academy of Sciences H-1111 Budapest Kende u 13-17 Hungary Department of Automation and Applied Informatics Budapest University of Technology and Economics H-1111 Budapest Hungary

We discuss a new generic optimal controller structure for raw material blending in the cement industry. We focus on an important phase of the proportioning-burning-grinding operation triplet that essentially determines the cement quality; namely, the composition control of the raw mill system. We begin by describing the application of a generic optimal controller structure to this important phase, followed by a discussion of the control engineering background and the design of the realized controller. Finally, the control algorithm is discussed in a technology-independent manner.

2003 IEEE Bologna PowerTech Conference

作者： Süto, Z. Nagy, I. Department of Automation and Applied Informatics Budapest University of Technology and Economics Budafoki út 8 Budapest H-1111 Hungary Computer and Automation Research Institute Hungarian Academy of Science Budapest Hungary

ISBN: (纸本)0780379675

The analysis, design aspects and numerical results of a current controlled three-phase Space Vector Modulated (SVM) Voltage Source Converter (VSC) are presented. The aim of the current controller of VSC is to track the balanced three-phase sinusoidal reference currents. The current controller includes a complex saturation function in order to avoid overmodulation in the SVM, Due to this strong nonlinearity the study leads to rather unexpected system states. An approximate Poincare map is derived using stroboscopic sampling with the modulation period of the SVM. Selecting eigenvalues of the system linearized around the desired fixed point is not sufficient to the proper operation. Other stable fixed points or limit cycles can appear. Chaotic states also can develop in the unstable region of the desired fixed point. The main objectives are to develop the tools for describing the nonlinear behavior, for designing the digital PI controller and to present numerical results. © 2003 IEEE.
