In this paper, a bias-correction least-squares (LS) algorithm is proposed for identifying block-oriented errors-in-variables nonlinear Hammerstein (EIV-Hammerstein) systems. The estimation bias caused by additive white noises in the EIV-Hammerstein system is addressed and a bias-estimation scheme based on noisy measurements is proposed for consistent parameter estimation. A specific algorithm based on minimizing the output prediction error is given to estimate the unknown noise variances. The effectiveness of the proposed method is demonstrated through simulation and experimental verification using a wireless power transfer system.
In this paper, a bias-correction least-squares (LS) algorithm is proposed for identifying block- oriented errors-in-variables nonlinear Hammerstein (EIV- Hammerstein) systems. Because both the input and output of the EIV-Hammerstein system are observed with additive white noises, the estimation bias of traditional LS algorithm is introduced. The estimation bias is derived from a consistency point of view, which is a function about noise variances and monomial of noiseless system input-output measurements. A bias-estimation scheme based only on the available noisy measurements is then proposed for consistent identification of the monomial of noiseless system input-output measurements in a recursive form. In particular, a specific algorithm based on minimizing the output prediction error is given to find out the unknown noise variances for practical applications, such that the noise effect can be eliminated and the consistent estimated parameters are obtained. The effectiveness of the proposed method is demonstrated by a simulation example and an experimental prototype of wireless power transfer system.

Robust lithium-ion state-of-charge and battery parameters joint estimation based on an enhanced adaptive unscented Kalman filter

Jie Hou, Jiawei Liu, Fengwei Chen, Penghua Li, Tao Zhang, Jincheng Jiang, Xiaolei Chen

Summary: This paper proposes a model and data uncertainties-robust method based on an enhanced adaptive unscented Kalman filter (AUKF) for simultaneous estimation of model parameters and battery state of charge (SOC). The method integrates all unknown variables using an extended state observer and obtains uncertain model and data statistics through a covariance matching technique with adaptive forgetting factor. The proposed method is more robust to model uncertainties and data uncertainties compared to conventional SOC estimation methods.

Consistent Subspace Identification of Errors-in-Variables Hammerstein Systems

Jie Hou, Hao Su, Chengpu Yu, Fengwei Chen, Penghua Li, Haofei Xie, Taifu Li

Summary: In this article, a consistent subspace identification method (SIM) is proposed for block-oriented errors-in-variables Hammerstein systems. The existing SIMs using parity subspace based on noisy measurements may result in biased parameter estimates. We propose a scheme for consistent system parameter estimation, which estimates the noise-free Hankel matrix using available noisy measurements and noise variances. The effectiveness and merits of the proposed method are supported by two simulation examples.

Receding Horizon D-Optimal Input Design for Identification of Wireless Power Transfer Systems

Zhifan Li, Qijun Deng, Fengwei Chen, Pan Sun, Jiangtao Liu, Wenshan Hu, Hong Zhou

Summary: This article proposes a method of input design for wireless power transfer (WPT) systems based on receding horizon D-optimization. The system's dynamic behavior is characterized by a discrete-time, single-input, single-output (SISO) model, and the model parameters are estimated using a recursive least-squares (RLS) method. The excitation signal of the system is designed based on receding horizon D-optimization to improve the quality of parameter estimates. The sequential quadratic programming (SQP) method is employed to solve the receding horizon D-optimization for improving convergence and efficiency of the input design process. Numerical and experimental results demonstrate the effectiveness of the proposed method.

A Double-Receiver Compact SCC-WPT SystemWith CV/CC Output for Mobile Devices Charging/Supply

Zhe Liu, Hongsheng Hu, Yu-Gang Su, Yue Sun, Fengwei Chen, Pengqi Deng

Summary: This article presents a double-receiver single capacitance coupled wireless power transfer system with a three-plate compact coupler to achieve free-position charging and superior system performance. The system consists of two independent receivers: one with a LCLC-S topology for constant-voltage output, and the other with a LCLC-M topology for constant-current output, without affecting each other. By circuit analysis and a simplified equivalent circuit of the three-plate coupler, the CV and CC characteristics are theoretically analyzed. The effectiveness of the proposed system is verified through prototype testing, showing stable output power for each receiver at any position within the transmitting plate.

Full-parameter constrained parsimonious subspace identification with steady-state information for DC-DC converters

Jie Hou, Zhen Yang, Taifu Li, Huiming Wang, Jincheng Jiang, Xiaolei Chen

Summary: A full-parameter constrained parsimonious subspace identification method is proposed to model the DC-DC converters, incorporating the steady-state a priori information. Compared with traditional data-driven methods, the subspace-based method can estimate both model structure and parameters simultaneously with appropriate computational complexity. Moreover, the proposed algorithm can accurately estimate the system parameters with a smaller variance compared to the traditional full-parameter constrained subspace approach. Experimental results on a DC-DC synchronous buck converter verify the effectiveness and superiority of the proposed method.

Interaction-Matrix Based Personalized Image Aesthetics Assessment

Jingwen Hou, Weisi Lin, Guanghui Yue, Weide Liu, Baoquan Zhao

Summary: Personalized image aesthetics assessment aims to estimate aesthetic experiences based on individual preferences. This research proposes a method that directly estimates personalized aesthetic experiences from the interaction between image contents and user preferences, without the need for prior knowledge on generic aesthetics assessment. Extensive experiments show that the proposed method outperforms previous personalized methods and generic methods in terms of both personalized and generic aesthetics assessment.
