A Novel Approach in Studying the Effects of Subharmonics on Ultrahigh-Speed AC Motor Drives

In the paper a comparative analysis is carried out on seven different self-excitation methods that have been developed in the past decades taking into account the technical and economical features of the methods compared. A novel solution based on resonant circuit application is described in more detail, and the theoretical considerations have been confirmed by computer simulations and laboratory test results *and nagy@get.bme.hu) Z.

“…For high-power drives with low switching frequency of converters (and for some control modes of high-speed drives) it is necessary to synchronize the output voltage waveforms of converters with its fundamental component, for minimization of undesirable sub-harmonics of voltage and current [7]- [9]. To provide voltage synchronization of inverters with spacevector PWM, specialized strategy of synchronized pulsewidth modulation (PWM) has been proposed for inverter control [10]- [11].…”

This paper presents description of peculiarities of operation (under specific control strategy) of multi-inverter sixphase drive with open-end windings, spatially shifted by 30 electric degrees. The control of four inverters of this system is based on the use of special switching sequences, allows insuring cancellation of common-mode voltage. In this case it is possible to use only two insulated dc sources in this multi-inverter topology. Symbiosis of specific control scheme with algorithms of synchronized space-vector modulation ensures voltage waveform symmetries during entire control range for any operation conditions of systems.

“…These so-called "X-by-wire" systems act as an interface between the driver and the targeted mechanical subsystem of the vehicle (e.g., brakes, throttle valve) [1]- [12]. Coupled with the use of advanced control strategies the "X-bywire" systems can, in general, provide wider functionality and better research and development in vehicle control techniques, such as electric braking control, posture stabilization control, longitudinal control of road vehicles, and electronic throttle (ET) valve control [13]- [15]. ET can replace its mechanical counterpart if a control loop satisfies prescribed requirements, which are a fast transient response without overshoot, positioning within the measurement resolution, and the control action that does not wear out the components [3].…”

In order to control the nonlinear hysteretic electronic throttle adopted in modern automobiles, a new result for the tracking control of nonlinear hysteretic system is first proposed in this paper. Therefore we can realize the intelligent fuzzy logic controller in a well-behaved and systematic manner. A new closed-loop Back-propagation tuning is also proposed for the tuning of the fuzzy output membership functions to yield better tracking result. Finally, the controller synthesis is performed in a real-time environment using dSpace MicroAutobox and advanced microcontroller development board to yield excellent tracking results with cost-effective implementation.Index Terms-Electronic throttle (ET), fuzzy logic, hysteretic systems, intelligent control.
