“…The lower computer utilizes the STM32F103 series microcontroller manufactured by STMicroelectronics to primarily control the electromagnet in the liquid suction component for simultaneous quantitative liquid suction in twelve channels, the stepper motor in the liquid discharge component for interval-based liquid dispensing, and the electromagnetic relay in the pipette head removal component for the simultaneous removal of pipette heads in twelve channels. Control of the stepper motor is primarily achieved through the microcontroller's internal timer, which generates Pulse-Width Modulation (PWM) signals [20], enabling the precise control of the stepper motor's rotation by configuring suitable PWM generation parameters according to the desired rotation angle and speed. When controlling the electromagnet and electromagnetic relay, relay components are employed.…”

In this study, to improve the efficiency of the pipetting workstation and reduce the impact of the pipetting device on the stability performance of the workstation, a novel fully automatic pipetting method is proposed. Based on this method, a lightweight, multifunctional, and quantitative twelve-channel pipetting device was designed. This device can achieve simultaneous quantitative liquid absorption for twelve channels and sequential interval liquid discharge for each channel. Initially, the overall functional requirements were determined, and with the aim of a lightweight design, the total weight of the device was controlled to be within 580 g through a reasonable structural design, material selection, and choice of driving source. The device’s overall dimensions are 170 mm × 70 mm × 180 mm (length × width × height), with a micropipetting volume ranging between 1.3 μL and 1.4 μL. Subsequently, factors affecting liquid suction stability were experimentally analyzed, and appropriate pipetting parameters were selected. The stability performance of this pipetting method during prolonged operation was investigated. Finally, the twelve-channel pipetting device was validated through experiments, demonstrating results that meet the national standards for the stability of a pipetting device. In summary, the device designed in this study exhibits novel design features, low cost, and modularity, thus demonstrating promising potential for applications in high-speed micro-volume pipetting.

<span lang="EN-US">The paper describes field oriented control strategy with space vector pulse width modulation technique of permanent magnet synchronous motor drive system for an electric vehicle. At first, mathematical models of the motor and the drive system for electric vehicle are presented. In order to obtain high performance drive and maximum motor torque, field oriented control strategy and space vector pulse width modulation technique method are applied to drive system in next section. Speed controller design utilizing the popular zero-pole elimination approach causes large integral constant time in case of small rotational damping constant. The desired-transient-response-based approach is employed to overcome the problem. Performance indices include overshoot, undershoot, steady-state speed error, and total harmonic distortion of stator current, are employed to assess the drive systems with two speed controller design methods. Theoretical assumptions are confirmed via simulations and criteria in MATLAB/Simulink environment.</span>

Leg Conversion Method for the Continuous Control of a Railway Vehicle Propulsion Inverter

et al. 2023

In this study, we propose a whole-leg scheme for the continuous control of a railway vehicle propulsion inverter. The three-leg method is commonly used to obtain the output AC power from the input DC voltage in a railway vehicle propulsion inverter. When the power semiconductor of an inverter operating in a three-leg manner fails, a problem occurs in the power supply. Therefore, this study proposes a method that automatically converts into the two-leg method without replacing the power semiconductor when it fails while the inverter is driven with the three-leg method. This leg conversion method can prevent problems in supplying power by converting the power that can be obtained from an inverter operating with the three-leg method into that obtained from an inverter operating with the two-leg method. In addition, to verify the effectiveness of the leg conversion method, a demonstrative experiment was conducted after a simulation, and an actual inverter was fabricated. Consequently, the experimental results confirmed that in an inverter operating with the three-leg method, even if the power semiconductor failed, it could be converted for operation with the two-leg method to supply power normally.
