   1.5-kW, 150,000-r/min Ultra High-Speed PM Motor Fed by 12-V Power Supply for Automotive Supercharger
By Toshihiko NOGUCHI, Tetsuro WADA [View]
[Download]

Abstract: This paper presents a 1.5-kW, 150,000-r/min PM motor fed by a 12-V power supply, which is applicable to an automotive supercharger. The motor is specially designed to improve its efficiency over 97 \% (excluding a mechanical loss) and to raise its power density to 13 W/cm3 at the same time. Feasibility of the design is confirmed through experimental tests, using a prototype motor.

   A Comparative Analysis of Total Harmonic Distortion in TPRD and RNSIC
By Constantin FILOTE, Calin CIUFUDEAN, Ana Maria COZGAREA [View]
[Download]

Abstract: The total harmonic distortion (THD) monitoring is an important challenge in the industrial and office building environment. The IEEE-519 and IEC 61000-3 standards limit the individual harmonics current as well as the THD for nonlinear power electronic loads. A harmonic current distortion comparative study of a classical three-phase rectifier diode (TPRD) and rectifier with near sinusoidal currents (RNSIC) are presented. Simulation results are experimentally verified.

   Energy optimal motion control of servo motors and downsizing of components
By Frederik KLENKE, Volkmar MÜLLER, Wilfried HOFMANN [View]
[Download]

Abstract: Servo drives comprise a significant potential of energy saving which has not been considered sufficiently up to now. Simple changes in the motion control of energy optimal and jerk limited motions can be implemented which lead to a reduced acceleration rms-value and slightly increased maximal acceleration. The resulting reduction factors for dimensions and moved masses lead even to further savings on thrust or torque whose value depend on load-side parameters.

   MODELING A TRANSISTOR CONVERTER-FED PERMANENT MAGNET POLY-PHASE MACHINE AND A VARIABLE-FREQUENCY DRIVE CONTROLLER UNDER NON-SINUSOIDAL BACK-EMF CONDITIONS
By Mikhail PRONIN, Oleg SHONIN, Alexey VORONTSOV, Grigory GOGOLEV, Sergey SHOPIN [View]
[Download]

Abstract: The paper presents a model of a poly-phase permanent magnet motor of the marine propulsion drive energized by multistage VSI. The model defines more precisely the non-sinusoidal waveform of back- EMF and its impact on the current distortion and electromagnetic torque ripples. The paper concludes by analyzing simulation results that have shown significant suppression of high order current harmonics and corresponding decrease in torque ripples due to the proposed control algorithm realized in a phase reference frame.

   Multilevel Converters for High Fundamental Frequency Application
By Luca D'ERRICO, Alessandro LIDOZZI, Vittoria SERRAO, luca SOLERO [View]
[Download]

Abstract: The proposed paper intends to investigate the benefits of using multilevel converters in high fundamental frequency applications as high speed electric drives, with particular reference to the energy recovering from gas exhaust in automotive systems. Waveforms and THD comparison of conventional two-level sine wave and Neutral Point Clamped converters have been developed and investigated by means of both simulation models and prototypal realization of a NPC three level threephase converter. Experimental analysis of power switches losses has been also carried out.

   Optimal Control for AC Drive with Quadratic Criteria
By Marian GAICEANU, Emil ROSU, Traian MUNTEANU, Teodor DUMITRIU, Romeo PADURARU, Cristinel DACHE [View]
[Download]

Abstract: The main result presented in this paper is the implementation of optimal control based on quadratic criteria into a low power electric drive with three-phase induction motor. The dSPACE 1104 controller has been used in order to obtain the on-line optimal solution of Matrix Riccati Differential Equation (MRDE). Based on the optimal solution and on corresponding feedback signals, the optimal speed reference for the AC drive system is obtained. The optimal speed reference is tracked by Altivar 71 inverter, conducting to energy reduction in AC drive. In order to highlight the performances obtained by electric drive, the classical control (consisting of rotor field oriented control with PI controller) and the optimal one have been implemented by designing an adequate ControlDesk interface. The three-phase induction machine (IM) is controlled at constant flux. Therefore, the linear dynamic mathematical model of the IM has been obtained. The comparative analysis of the AC drive system conducted by the optimal control and by classical one reveals the optimal control advantages. The optimal control law provides smooth transient regimes with minimal energy consumption. The constraints of the control and state magnitude can be solved by adequate choice of the weighting matrices of the adopted performance functional. The obtained solution, by integration of the MRDE, is orientated towards the numerical implementation-by using a zero order hold. The implemented test bench system is very useful to researchers, doctoral students or experts training in electrical drive. The analysis of optimal control solution and the influences of the weighting matrices are shown through the experimental results.

   THE OPTIMAL CONTROL FOR POSITION DRIVE SYSTEM WITH INDUCTION MACHINE
By Traian MUNTEANU, Emil ROSU, Marian GAICEANU, Romeo PADURARU, Teodor DUMITRIU, Mihai CULEA, Cristinel DACHE [View]
[Download]

Abstract: This paper illustrates the importance of control on energy saving opportunity in electrical drives systems. The paper’s objective is to develop an optimal control law for an electrical position drive systems with induction machine (IM) using a voltage source inverter. The optimal control provides dynamic regimes with minimum input energy and performs the minimization of the copper losses from IM. The solution of the problem uses optimal control theory and the numerical integration of the matrix Riccati differential equation (RMDE). The synthesis of the optimal energetic control law is accomplished by comparing, via simulation, the two control methods: conventional and optimal.
