A trunnion joint is modeled as a circular plate with a rotational spring at the outer peripheral portion to resist rotation. Asymmetrical bending deflection is produced when an external moment acts on the inner side of the circular plate. The equations of the circular plate with a special outer peripheral boundary condition are derived. Choosing the stiffness of the rotational spring and the ratio...
This paper reviewed the main stream of commercial software for electric vehicle simulation and briefly discussed the advantage of physical modeling tool. A dynamic simulation model of electric vehicle (EV) was developed using Matlab/Simulink and SimPowerSystem/SimDriveline toolbox. The EV model has a configurable structure that is suitable to simulation with multiple fidelity levels. This advantage...
For high resolution spaceborne SAR system, the errors caused by straight trajectory assumption and stop-go approximation cannot be ignored. In this paper, an algorithm is proposed to compensate the above errors. First, a novel modified hyperbolic range equation (MHRE) is introduced to describe the satellite's orbit which is more precise than the traditional hyperbolic range equation (THRE). Then,...
This paper deals with the problem of azimuth imaging worsening when three-step focusing algorithm fulfills imaging requirements of sliding spotlight SAR with wide azimuth swath. This is caused by spaceborne sliding spotlight SAR spatial variation characteristic: single point target's relatively large range cell migration and azimuth point targets' different Doppler experiences at different azimuth...
In this paper, a robust adaptive control strategy using a fuzzy compensator for MEMS triaxial gyroscope, which has system nonlinearities, including model uncertainties and external disturbances, is proposed. A fuzzy logic controller that could compensate for the model uncertainties and external disturbances is incorporated into the adaptive control scheme in the Lyapunov framework. The proposed adaptive...
Leakage current (LC) and environmental data online monitoring system are installed in 6 substations in Shenzhen, which can measure simultaneously post insulators LC and environment temperature, humidity, wind speed, rainfall amount and wind direction. This paper presents the predict results of LC from the environmental data using linear and nonlinear regression. The results show that although the...
In this paper, some new concepts are presented. We propose a model of point set for urban transport, which can provide us the choices of one bus station to another bus station. This model may be helpful for solving the optimization problems of urban transport in some sense.
Tension control and precise conveyance in web-handling machines are critical to ensure product quality. This paper is focused on actualizing a hybrid control method of tension and position for a discontinuous web transport system. First, the simplified algebraic dynamical models of the unwind/rewind section and feed section are presented, which plays an important role for the moving control of flexible...
KIII model is an olfactory neural networks bionic model proposed by Walter J. Freeman. Its architecture simulates that of olfactory neural system, which is different from other artificial neural networks. Through simplifying KIII model, a color texture generating algorithm is proposed combining with RGB. In RGB space, the tricolor of each pixel (red, green and blue) is used as the model input and...
