“…(1) Phase Current Detection Circuit Design: Common phase current detection methods in AC servo control platforms mainly include Hall element sampling, sampling resistance, magnetoresistance sampling, and DC mutual inductance sampling [23]. Among them, resistance sampling is divided into single resistance sampling and three resistance samplings.…”

A dual-servo drive and control integrated platform based on VNet neural network development is aimed to address the concerns of poor realization function, operational stability, and lengthy reaction time in the presently built dual-servo drive and control integrated platform. The VNet neural network model structure is established, the VNet neural network model is trained, and the VNet neural network adaptive control method is introduced. Based on VNet neural network development, the hardware design of the dual servo drive control integrated platform has been completed through the overall hardware architecture of the platform, power drive circuit design, and control unit circuit design. The control program was developed using the C language based on a combination of STM32F4 library functions. Through the overall structure of the platform software, the design of functional modules and the design of the servo drive controller, the software design of the dual-servo drive and control integrated platform is completed, and the dual-servo drive and control integrated platform design is realized. The experimental results show that the proposed method design platform’s implementation function and operational stability are good, and the platform response time can be effectively shortened.

“…In this paper, fault occurrence is detected using oscillation of the d e q e -axis current feedback during faults. Additionally, since the two sets of neutral points are separated, the fault phase was detected using Kirchhoff's current law [31][32][33][34][35][36].…”

Hybrid Mode Control of an Asymmetric Dual Three-Phase Synchronous Motor Under Single-Phase Open Fault

et al. 2022

This paper proposes hybrid mode control for an asymmetric dual three-phase synchronous motor (ADTP-SM) with separated neutral points in a single-phase open-fault situation. The fault-tolerant control is classified into the maximum torque mode and minimum loss mode. For an arbitrary phase with an open fault, the combination of phase currents for operation in each mode is derived by mathematical analysis. In maximum torque mode operation, a rotational coordinate transformation is proposed to minimize the performance variance according to the speed. In minimum loss mode operation, a stationary coordinate transformation is proposed to control the harmonics of the phase currents. This stationary coordinate transformation can be applied to arbitrary-phase open-fault situations. In addition, the performances with and without harmonic control are compared and analyzed, and the smoothness of the mode conversion is also analyzed. The validity of the proposed coordinate transformations is verified through experiments at various speeds.

“…As a result, the current sensor operates in the narrow range, e.g. the voltage drop corresponding to the current varying from zero to the rated value is 0~0.5 V [23]. The digitalization of this low-voltage signal with a built-in ADCs of microcontrollers, which are typically 10-or 12-bit, results in high discretization errors, therefore the signals from the shunts are typically preamplified and only after that, are sent to the ADC [24].…”

Nowadays the percentage of power electronic devices, which use shunts for sensing of electrical signals, is increasing significantly. This method of measurements is simple, reliable and low-cost, however it requires careful elaboration of schematics and meticulous design of printed circuit boards. The author provides a detailed insight into the design of power converter Printed Circuit Boards (PCBs) with shunt-based sensing circuits and provides recommendations on improvement of signal measurements. He analyses the most popular design mistakes and illustrates their impact on measuring signals, which can be used for mistake localization. This paper demonstrates that the properly designed schematic can be turned into poorly operating PCB and recommends measures to avoid it. The author shares his more than 20-years experience and illustrates his statements with examples from real life. Although this paper is mainly addressed to young engineers, it could also be useful for experienced researchers, who work in neighboring areas and do not gain experience in PCB design.
