  • Evaluation of lithium-ion synergetic battery pAck as battery charger
    IEEE Transactions on Energy Conversion, 1999
    Co-Authors: A. Davis, Ziyad M Salameh, S.s. Eaves
    Abstract:

    A new battery configuration technique and Accompanying control circuitry, termed a synergetic battery pAck (SBP), is designed to work with lithium batteries, and can be used as both an inverter for an electric vehicle Ac Induction Motor drive and a battery charger. In this paper, the authors compare the performance of the synergetic battery pAck as a battery charger with several simple conventional battery charging circuits via computer simulation. The fActors of comparison were power fActor, harmonic distortion and circuit efficiency. The simulations showed that the SBP is superior to conventional charging circuits since the power fActor is unity and harmonic distortion is negligible.

  • Comparison of a synergetic battery pAck drive system to a pulse width modulated Ac Induction Motor drive for an electric vehicle
    IEEE Transactions on Energy Conversion, 1999
    Co-Authors: A. Davis, Ziyad M Salameh, S.s. Eaves
    Abstract:

    A new battery configuration technique and Accompanying control circuitry, termed a synergetic battery pAck (SBP), is designed to work with lithium batteries, and can be used as both an inverter for an electric vehicle Ac Induction Motor drive and as a battery charger. In this paper, the performance of a synergetic battery pAck during Motor drive operation is compared via computer simulation with a conventional Motor drive which uses sinusoidal pulse width modulation (SPWM) to determine its effectiveness as a Motor drive. The study showed that the drive efficiency was compatible with the conventional system, and offered a significant advantage in the lower frequency operating ranges. The voltage total harmonic distortion (THD) of the SBP was significantly lower than the PWM drive output, but the current THD was slightly higher due to the shape of the harmonic spectrum. In conclusion, the SBP is an effective alternative to a conventional drive, but the real advantage lies in its battery management capabilities and charger operation.

  • application of servo controller design for speed control of Ac Induction Motors using polynomial differential operator
    , 2016
    Co-Authors: Dae Hwan Kim, Phuc Thinh Doan, Pandu Sandi Pratama, Van Tu Duong, Jung Hu Min, Young Seok Jung, Sang Bong Kim
    Abstract:

    This paper proposes a servo controller design method for speed control of Ac Induction Motors using polynomial differential operator. To do this task, the followings are done. First, nonlinear modeling for an Induction Motor is introduced and is linearized at equilibrium points using Taylor’s series. Second, an observer is designed to estimate flux, and an extended system incorporating the internal model principle to construct the extended system is shown using polynomial differential operator in case that the types of reference inputs are differential polynomials. Third, a state feedbAck control law for the extended system to trAck the given reference input is designed by a regulator design method. A control system is constructed for speed control of the 1.5 KW Ac Induction Motor. The simulation and experimental results are shown to verify the applicability of the proposed controller compared to conventional PI controller for the Ac Induction Motor with a step type of disturbance to trAck its speed of 3 types of the references such as step, ramp and parabola.

  • Sensorless Vector Control of Ac Induction Motor Using Sliding-Mode Observer
    International Journal of Science and Engineering, 2013
    Co-Authors: Phuc Thinh Doan, Tan Tien Nguyen, Sang Kwun Jeong, Sang Bong Kim
    Abstract:

    This paper develops a sensorless vector controlled method for Ac Induction Motor using sliding-mode observer. For developing the control algorithm, modeling of Ac Induction Motor is presented. After that, a sliding mode observer is proposed to estimate the Motor speed, the rotor flux, the angular position of the rotor flux and the Motor torque from monitored stator voltages and currents. The use of the nonlinear sliding mode observer provides very good performance for both low and high speed Motor operation. Furthermore, the proposed system is robust in Motor losses and load variations. The convergence of the proposed observer is obtained using the Lyapunov theory. Hardware and software for simulation and experiment of the Ac Induction Motor drive are introduced. The hardware consists of a 1.5kw Ac Induction Motor connected in series with a torque sensor and a powder brake. A controller is developed based on DSP TMS320F28355. The simulation and experimental results illustrate that fast torque and speed response with small torque ripples can be Achieved. The proposed control scheme is suitable to the application fields that require high performance of torque response such as electric vehicles.
