Simulation of the Electro-hydraulic Control of Wet Clutch Actuator by Zhang Zengliang

“…To the problems of strong nonlinear,time delay and lower control accuracy of wet clutch actuator,an automobile automatic transmission with wet clutch actuator is studied,according to the characteristics of the wet clutch and control strategy requirement,a wet clutch electro-hydraulic actuator control model is established,the simulation is carried out with Matlab/Simulink software.The results show that the charge phase,the displacement of electric hydraulic valve plunger and clutch,the clutch flow to achieve maximum positive displacement first,and gradually decreases stabilized.In the discharge phase,the displacement of electric hydraulic valve plunger and clutch,the clutch flow to achieve maximum negative displacement first,and gradually increased to stabilize,and the overall trend is consistent with the input current.In different times have different average delay time,and the delay time will reduce the control precision control of systems.The different control accuracy generate in different controllers and predictive control policies.…”

An Optimization to Schedule Train Operations with Phase-Regular Framework for Intercity Rail Lines by Huimin Niu, Minghui Zhang

“…This paper proposes a phase-regular scheduling method which divides a day equally into several time blocks and applies a regular train-departing interval and the same train length for each period under the period-dependent demand conditions. A nonlinear mixed zero-one programming model, which could accurately calculate the passenger waiting time and the in-train crowded cost, is developed in this study. …”

Self-adaptive encryption algorithm for image based on affine and composed chaos by Chang-ci WEN, Qin WANG, Fu-min HUANG, Zhi-shu YUAN, Chun-sheng TAO

“…On the basis of three-dimensional affine transformation in limited integer domain and composed chaos,a novel digital image encryption algorithm was proposed.Firstly,it scrambled pixels’ position and confused pixels’ value according to corresponding coordination.Secondly,it took a series of nonlinear diffusion,substitution and re-diffusion.In the process of substitution,it introduced pixels’ value to perturb multiple chaos systems that were coupled together for self-adaptive encryption.The algorithm proceeded the above two steps for 3 times to defend chosen plaintext attack,and had huge key space to defend violent attack.The scrambling function in it was compatible with images at any ratio of length to width without any preprocessing; the constructed whole chaos system which had a simple form was designed modularly,and could be realized parallel conveniently.…”

CSI feedback algorithm based on RM-Net for massive MIMO systems in high-speed mobile environment by Yong LIAO, Shiyi WANG

“…Aiming at the complex and changeable channel characteristics in high-speed mobile environment, and the influence of additive noise and nonlinear effects, a residual mixing network (RM-Net) for massive MIMO CSI feedback was proposed.By learning the spatial structure and temporal correlation of high-speed mobile channel, the network was able to remove massive MIMO channel noise, and the CSI compression rate and recovery quality could be significantly improved.System simulation results show that RM-Net can eliminate the influence of additive noise in high-speed mobile scenarios, learn and adapt to the channel characteristics of sparse and double-selective fading channels, and still has good performance under the conditions of high compression rate and low signal-to-noise ratio.The proposed algorithm performance is much better than other CS-based and DL-based CSI feedback algorithms.…”

Requirements-oriented spectrum sharing for OFDMA cognitive radio networks by Chi ZHANG, Bi-qing ZENG, Jin-song YANG, Xiao-hong XIE

“…Considering the satisfaction of the secondary network communication requirements,a two-stage model was proposed to address the spectrum leasing and allocation problem in OFDMA cognitive radio networks(CRN).At the first stage of the model,the secondary base station(SBS)collected channel capacity requirements of the secondary network,and rent the spectrum resource from multiple primary base stations(PBS).The trade behaviors between the PBS and the SBS were modeled with a Bertrand game,and adopted the Nash equilibrium as the pricing scheme.At the second stage,with the Nash bargaining solution(NBS),the subcarriers and power allocation problem were defined as a nonlinear programming problem,and obtained the solution by Lagrange multiplier method.Comparing with the other spectrum allocation schemes,simulation results show the proposed spectrum sharing scheme can satisfy each secondary user’s communication requirements more fairly and efficiently.…”
