A parameter-optimized reinforcement iterative learning control method for enhancing passenger pressure comfort and air quality in high-speed trains traversing extreme tunnels

Lu Yang, Chunjun Chen, K. Yin, Boyuan Mu

When high-speed trains traverse tunnels with characteristics such as high altitude, steep gradients, and substantial lengths, intense tunnel pressure waves are generated. These pressure waves induce pressure fluctuations within the carriage, adversely affecting passenger pressure comfort. However, when trains pass through extra-long …

Eye movement predictors of hazard response performance in train drivers under different speed conditions

Lu Yang, Maosheng Xia, Yusong Wang, Fang Ding et autres

Foreign objects on railroads contribute to railway accidents. Train driving heavily relies on visual prowess. Drivers must quickly identify and react to these hazards, capabilities that directly impact the safety and efficiency of train operations. As train speeds increase, it becomes increasingly …

Dietary adaptations and nutritional shift of Alpine musk deer in Helan mountains, north China

Zhirong Zhang, Chang Zhao, Yun Su, Baojun Zhang et autres

The Alpine musk deer ( Moschus chrysogaster ), an endangered species with fewer than 200 individuals in fragmented habitats of the Helan mountains, faces pronounced seasonal resource fluctuations. This study investigates seasonal shifts in diet composition, nutrient intake, and tolerance to secondary …

An Adaptive-Gain Reinforcement Iterative Learning Control Scheme for Nonlinear Systems to Track Morphologically Similar Targets

Chunjun Chen, Lu Yang, K. Yin, Yaowen Zhang

This paper investigates the problem of tracking morphologically similar targets for nonlinear systems and proposes an adaptive-gain reinforcement iterative learning control (AG-RILC) scheme. Unlike existing control approaches, where gain schemes are predefined before the control process, this study incorporates a reinforcement learning …

Performance iterative learning control on nonlinear systems for tracking varying-scale and morphologically similar targets

Lu Yang, Chunjun Chen, Ji Deng, Boyuan Mu et autres

This paper proposes a novel three-dimensional (3D) performance iterative learning control (PILC) scheme on nonlinear systems for tracking varying-scale and morphologically similar targets. The condition and performance weighted K-nearest neighbour (KNN) and the historical database update algorithms are developed to match the …

Modeling Multi-Factor Coupled Pressure Fluctuations in EMU Trains under Extreme Tunnel Conditions

Miao Zou, Chunjun Chen, Lu Yang

As an electric multiple unit (EMU) train passes through an extreme tunnel characterized by high altitude, steep gradient, and extended lengths, the pressure waves generated by the train–tunnel aerodynamic coupling combine with the baseline pressure variations within the tunnel. This interaction results …
