In order to reduce the computational complexity of the electrochemical modelling of lithium-ion batteries and improve the computational speed, this paper proposes a simplification method for the modelling of lithium-ion batteries. Based on the existed single particle model of lithium-ion battery, this article simplifies the solid-liquid diffusion process and proposes an extended single particle model. Simulation based on COMSOL is performed to verify the proposed model. Compared with the full order electrochemical model, the calculation speed of the proposed method under 1C discharge rate only takes 0.6054 seconds, which is only 10.9% of P2D. In addition, the mean square error under constant current condition is 2.95 mV only, and the dynamic condition error is 10.12 mV. The results verify the superiority of the proposed model in calculation speed with enough accuracy. © 2023 IEEE.

To address the issue of vehicle speed estimation, particularly at low speeds, applicable to various environmental conditions, especially in the absence of driven wheels for vehicles equipped with four-wheel drive systems, a rule-based wheel speed identification and vehicle speed estimation method is proposed. This technique leverages wheel speed sensors and longitudinal acceleration sensors for vehicles to enhance the precision of wheel speed identification at low speeds and enhance the adaptability of vehicle speed estimation under different conditions. Firstly, to tackle the problem of no wheel speed pulse signal passing within one sampling period at low speeds, estimation is achieved through time accumulation, enabling effective wheel speed identification for both high and low-speed. Furthermore, utilizing the Kalman filtering algorithm and Butterworth filter, the wheel speed and wheel acceleration are filtered separately to reduce signal fluctuations caused by noise interference, thereby providing reliable input signals for estimating vehicle speed. Building upon this, A method for estimating vehicle speed based on the gradient constraint approach is proposed, taking into account the sequential relationships of each wheel speed and the longitudinal acceleration signal. Finally, real vehicle tests under different conditions demonstrate that the proposed vehicle speed estimation technique achieves high estimation accuracy, meeting the vehicle's speed estimation requirements under various environmental factors. © 2024 IEEE.

In recent years, the rise of electric vehicles (EVs) has brought Active Sound Design (ASD) to the forefront as a crucial methodology for enhancing both acoustic quality and the overall driving experience. To address the challenges associated with sound quality design in electric vehicles, an offline simulation software for Active Sound Design (ASD) systems has been developed using the MATLAB platform in this paper, where the vehicle dynamics model and three distinct sound synthesis algorithms have been incorporated into the software, and the formulation and modification of ASD system control strategies can be implemented. The simulations of vehicle operating conditions can be performed, the acoustic performance of the ASD system can be evaluated, and control strategies can be modified expeditiously based on the software developed in this paper. Moreover, the software supports integration with a Digital Signal Processing (DSP) hardware platform, facilitating a seamless closed-loop from sound design to real vehicle application, which contribute to substantially enhance the efficiency of ASD system development. The practical application effect of the software developed are further demonstrated on the electric SUV model, and the results show that the sound of the real vehicle test is the same as that of the software design, which proves its effectiveness and practicability in the active sound design of the vehicle. © 2024 IEEE.

Hybrid Position-Force Feed Control of Heavy Load Forming Nonapod for Manufacturing Thin Wall and High Rib Parts

引用

IEEE/ASME Transactions on Mechatronics 2024年

作者： Zheng, Fangyan Han, Xinghui Hua, Lin Zhuang, Wuhao Wuhan University of Technology Hubei Key Laboratory of Advanced Technology for Automotive Components Wuhan430070 China

As load-bearing structures, thin wall and high rib parts (TWHRP) are widely used in aerospace equipment. A novel envelope forming process and the corresponding forming Nonapod with a parallel kinematic mechanism are developed for the manufacture of TWHRP. To realize high formability, tracking of tool motion and forming force simultaneously is necessary. However, the existing force-position control method utilizes an elastic contact model (spring-damper system), which cannot model the plastic forming force, making the existing force-position control method fail in the plastic force process. Therefore, in order to achieve force control along the feed direction and position control along other directions, a novel hybrid position-force feed control method (HPFCM) suitable for the envelope forming process is proposed. By taking into account both the change of link pose sourced from the feed motion and the deformation of the link caused by the forming load, rigid-flexible coupling dynamic model for high-precision motion tracking is established. By demonstrating that the normal forming force exhibits a near-linear relation with the contact area and assuming constant parameters for frictional forming force in consecutive control cycles, a real-time forming load prediction model based on the current force state and cone-disk plastic deformation hypothesis is developed for quick response force tracking. Through calculation of real-time forming load, forward of forming feed rate, and three-loop control of servo motors, an HPFCM is realized, tailored for the heavy load envelope forming process. Finally, aircraft bevel gears and aircraft window frames are formed with high precision. Compared to the position control method, the part error, forming load, and process time are highly reduced with HPFCM. This result shows high formability in the envelope forming of TWHRP and promising application prospects of the proposed HPFCM. © 2024 IEEE.
