The pulse width modulation (PWM) technique is extensively employed in permanent magnet synchronous motor (PMSM) drives, which is classified into continuous PWM and discontinuous PWM (DPWM). The continuous PWM is more prevalent in PMSM drives, however, its performance diminishes notably in the high modulation index region compared to DPWM. In this paper, a novel DPWM method is proposed to enhance PMSM performance in the high modulation index region. According to the simulation and experiment results, it is demonstrated that the proposed DPWM method exhibits reduced high-order harmonics in this region compared to other DPWM strategies like DPWMMIN, DPWMMAX, and DPWM3. Additionally, a mixed PWM strategy is introduced and implemented in 12-V PMSM drives. The relative results indicate that space vector PWM (SVPWM) is utilized in the low modulation index region and transitions to the novel DPWM in the high modulation index region, resulting in reduced harmonics throughout the control process. © 2024 IEEE.

Permanent magnet synchronous machines have advantages such as small size, light weight, high efficiency, etc. It is more and more widely used in robots, electromagnetic propulsion, electric vehicles and so on. High power density and high torque density are urgent need for those applications. The electromagnetic design of machines mostly adopt multi-pole magnet patterns to reduce the stator yoke size. It helps to decrease the mass of the machine with the same power and improve the torque density. As the number of poles grows larger, the frequency and the core loss of per unit volume will also increase with the same speed, which can aggravate the heat problem of the machine. It is easy to generate the low-order vibration with high flux density. Therefore, the performance of a special-shaped external-rotor machine and comparisons with the traditional machine are analyzed in this paper. Numerical simulation is conduced to validated that the special-shaped magnet pattern can reduce the torque ripple, improve the torque output and power density. From the two-dimensional Fourier analysis of the radial electromagnetic force, it is found that the low-order amplitude of the special-shaped machine is greatly reduced, so the vibration can be avoided. Subsequently, the vibration simulation is carried out to indicate that the magnet pattern can satisfy low level in vibration and noise of the machine. © 2023 IEEE.

2021 International Conference on Mechatronics technology and Aerospace Engineering, ICMTAE 2021

作者： Liang, Xingzhuang Xu, Yu Wang, Jian State Key Laboratory of Fire Science University of Science and Technology of China Hefei230026 China AVIC Shenyang Aircraft Design and Research Institute Shenyang110035 China Key Laboratory of Aircraft Environment Control and Life Support MIIT Nanjing University of Aeronautics and Astronautics Nanjing210016 China

With the miniaturization of airborne system, heat dissipation has become a critical issue. Since sinusoidal channel can enhance flow disturbance, it has a stronger heat exchange capacity than that of straight channel. However, flow boiling characteristics in sinusoidal channel are more complex. Here, numerical simulations of flow boiling in sinusoidal and straight microchannels are conducted based on the VOF model with the inner diameter of 1 mm, mass flux of 500 kg/m2 s and heat flux of 50 kW/m2. The effects of channel structure and hypergravity are obtained. The simulation results indicate that bubble evolution in sinusoidal channel is more complex than that in straight channel, and bubbles are more likely to coalesce, deform and break. Vortices appear in sinusoidal channel and disrupt the near-wall boundary layer. Bubble evolution combined with vortices affect the flow boiling performances. For straight channel, dryout is less likely to occur, while for sinusoidal channel, it is more likely due to more drastic flow changes. Furthermore, the transition of flow patterns is faster under hypergravity. For sinusoidal channel, flow patterns transform earlier into slug and circular flows. © Published under licence by IOP Publishing Ltd.

With the development of multi-electrochemical aircraft, the application of electro-hydrostatic actuators(EHA) in aircraft actuator system is increasing. The dynamic stiffness of the actuator has a non-negligible effect on the fluttering characteristics of the rudder surface. So it is necessary to study the dynamic stiffness of EHA. In this research, a method for calculating the dynamic stiffness of EHA is proposed. The mathematical model of EHA is established. The bulk modulus of hydraulic oil affected by gas content and pressure is added to the model. Build the simulation model in Simulink. The dynamic stiffness of EHA is simulated in frequency domain. Analyze the simulation results. The EHA dynamic stiffness decreases with the increase of hydraulic oil gas content in the whole frequency range. The trough frequency of dynamic stiffness amplitude decreases with the increase of hydraulic oil gas content. The EHA dynamic stiffness decreases with the increase of pump leakage coefficient in low frequency band. Therefore, in order to improve the dynamic stiffness of EHA, the hydraulic oil gas content and the piston pump leakage coefficient should be reduced. © 2023 IEEE.

It is the first time that domestic civil large aircraft has been developed, which lacks the technical experience of airborne system-level airworthiness qualification, and the research of radiation emission at home and abroad is mainly based on simulation evaluation, while the simulation results are used only as a reference in the airworthiness qualification process and cannot be used as evidence of conformity. And there is little airworthiness test experience on complex system-level. In this paper, taking civil aircraft flight control electronic system as an example, through the demonstration of the airworthiness requirement, the description of the complexity of civil aircraft flight control electronic system, demonstrate the airworthiness qualification test and optimization process, providing experience for the airworthiness qualification of civil aircraft complex system. The results show that the radiation emission of flight control electronic system is greatly affected by the system environment, and it is necessary to consider the test setup layout and show the system compliance to the DO-160G requirements. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper investigates the physical layer security in wireless communication networks, focusing on the scenario where a base station sends confidential messages to a legitimate node while facing potential eavesdropping. The study assumes that the channel state information for both authorized and unauthorized nodes is not available. To assess both security and reliability, the paper introduces the use of bit error rate (BER) as a quantifiable security metric. The objective of the research is to evaluate the security performance improvement of the system through BER. Specifically, the impact of artificial noise (AN) power allocation ratio, and the number of transceiver antennas on BER performance is characterized. The numerical results demonstrate that artificial noise is effective against unknown passive eavesdropping attacks and leads to significant performance gains. For instance, by transmitting artificial noise power at approximately 50% of the total power to deliberately impair the eavesdropper’s reception, the BER gap between intended and unauthorized users can reach 0.4. © 2023 SPIE.

With the rapid development of traffic intelligence, autonomous driving technology has gradually attracted the interests of researchers. Behavioral decision-making is one of the most important parts of autonomous driving system (ADS). As a common solution, imitation learning (IL) provides a more natural and intuitive way of learning through the prior knowledge of experts. Generative adversarial imitation learning(GAIL), which is a branch of IL, is often used to learn the driving policy because of its robustness and capacity of handling large-scale problems. However, modal collapse caused by GAIL may make the generated policies lack diversity resulting in the failure of multi-task learning. In the paper, we propose an algorithm named as bidirectional generative adversarial imitation learning (BiGAIL) that allows the agent to learn the map between task intentions and driving policies, so as to achieve the goal of learning intention-based driving policy. Through simulation verification, the agent trained with BiGAIL is able to select the appropriate policy based on the current environment and learn different driving policies from multi-task demonstrations. © 2022 IEEE.

This paper presents the design of an high speed permanent magnet synchronous motor (PMSM) with a rated speed at 20000rpm applied to the Electro-Hydrostatic Actuator(EHA). Considering the full speed operating condition of the high-speed PMSM, the analysis is carried out through bearing selection, electromagnetic design, loss analysis and so on. To ensure motor output performance and reliability, this paper uses the finite element analysis to optimize the design of the EHA drive motor. Most importantly, in order to ensure high efficiency of the motor, detailed loss analysis and modeling are carried out. Finally, by optimizing the heat dissipation mechanism, the normal working temperature of the motor is ensured under all working conditions. © 2022 IET Conference Proceedings. All rights reserved.

This paper proposes a distributed tracking framework for high-maneuvering and malicious maneuvering target based on the sensor network. Considering some of sensors in the network can only observe partial system output, the collective observability is guaranteed. Based on the collective observability, the distributed target tracking algorithm is designed by local filter phase and consensus fusion phase. In local filter phase, the local estimate results can be obtained by each sensor node. Based on the target kinematic and sensor observation equations, the Kalman-like estimation algorithm is proposed to obtain the local estimate results. In most of the exist distributed state estimation (DSE) algorithms, the excellent target tracking performance is based on the assumption that the fusion times is infinity in consensus fusion phase. In practical application, however, the consensus fusion phase should be completed during two sampling instants. Besides, based on the finite-time stability theory, the error covariance matrix is processed as the solution of discrete-time algebraic Riccati equation (DARE). Then the stability of the proposed algorithm with finite-time consensus fusion is analyzed. Finally, a numerical example for tracking maneuvering target is given to validate the effectiveness. © 2023 Technical Committee on control Theory, Chinese Association of Automation.
