   Design of the Speed Sensorless Field Oriented Control System for Induction Motors Considering Sudden Change of the Rotor Speed
By Yoshiki SAKURAZAWA [View]
[Download]

Abstract: This paper studies design of the speed sensorless field oriented control of induction motors considering sudden change of the rotor speed. The controller gains are designed to follow the dynamics of the sudden change of the rotor speed based on an induction motor and current control system model. The primary angular frequency can be estimated properly even when the rotor speed changed suddenly by designing the controller. Also, the time to converge to the command values of the stator current and motor torque is shortened. The effectiveness of the designing method is evaluated by means of simulating slip of the railway vehicle traction.

By Tianqing WANG [View]
[Download]

Abstract: To address the chattering and steady-state error, this paper proposed a discrete super-twisting sliding mode current controller for induction motor drives. The backward difference of state error is introduced into the sliding mode surface combined with the discrete super-twisting control law. The experiments confirm the effectiveness of the proposed method.

   Dynamic Characteristics Verification of Linear Induction Motor by Simultaneous Propulsion and Levitation Control
By Shota NAKATANI [View]
[Download]

Abstract: This paper introduces a magnetic levitation transportation system driven only by linear induction motors. We propose a propulsion and levitation control with two frequency components acting simultaneously and independently. One of the frequency components controls propulsion. The other frequency component controls levitation. Because each controller is non-interfering with each other, this proposed control strategy simplifies the controller. The response of speed and air gap is confirmed by the experiment. As a result, the proposed system is able to control propulsion and levitation simultaneously and independently.

   Improvement of Driving Efficiency of PMSM by using Modified Trapezoidal Modulating Signal
By Kento BETTO [View]
[Download]

Abstract: This paper focuses on improving the efficiency of PMSM for electric vehicles. As a solution, this paper proposes a modulation method to be able to achieve three advantages. This control method provides three advantages, and two of which have been verified by conventional research: torque ripple reduction and increased torque. Therefore, this time, in addition to these two advantages, it was verified whether the third advantage, reducing inverter switching losses, is possible.

   Proposal of Boost converter without reactor using Open-ended Winding PMSM for Photovoltaic Pump System
By Akihiro OKAZAKI [View]
[Download]

Abstract: The way to use of clean energy is promoted actively, improving this system is important to solve environment issues. In photovoltaic pump system, voltage to work that system is generated by chopper circuit. However, in this system, there is problem that increase of cost and upsizing by chopper circuit for boost converter. In this paper, we propose the system to replace a reactor in chopper circuit with three phase windings of the open-ended winding PMSM.

   The Proposal of discriminating stable control bandwidth using ANN in sensorless speed control system for PMSM
By Ami TANAKA [View]
[Download]

Abstract: In the sensorless control of a permanent magnet synchronous motor (PMSM), there is a method of determining stability by analyzing the pole placement of the closed-loop transfer function regarding the influence of the three control bandwidths of current control, speed control, and sensorless control on stability. However, due to various effects, there is a problem that the theoretical analysis and the range of the control bandwidth that can be stably driven in the actual machine do not match. In this paper, we propose a method using ANN (Artificial Neural Network) in order to determine the condition of the stable control band more accurately.
