Arterial pulse waveforms contain a wealth of information about the cardiovascular system. There is a lack of physical meaning in the mathematical model of arterial pulse waves, while the physical model fails to offer individuality as too many assumptions are involved. In this article, we focus on promoting the interpretability of the arterial pulse mathematical model. The proposed method is based...
In order to save energy and improve the driving distance of electric vehicle, a regenerative braking control strategy based on fuzzy control for the electric vehicle with four in-wheel motors is proposed in this paper. Firstly, the braking force is distributed between front axis and rear axis to ensure the safety and stability of the vehicle. Secondly, the braking force is distributed between hydraulic...
Due to the strongly coupled characteristics of permanent magnet synchronous motors(PMSM), the feedback linearization method is presented to decouple the torque current and the flux current in the dynamic state, and control both currents respectively to achieve a quick and precise torque tracking control. Then, the effectiveness of the control method is validated by an effective simulation model of...
This paper will establish the simulation model and the inverter model of induction motor based on the multi function simulation software AMESim. Considering the influence on the motor from the temperature and other complex factors, and Using Matlab / Simulink software to establish a simulation model of direct torque control system, then we go on combined simulation through the combination of the two...
To gain the absolute vehicle slide angle is the key issue in security control system of vehicle. An adaptive Kalman filter based on Field Programmable Gate Array (FPGA) for vehicle slide angle estimation is presented in the paper. Firstly, the mathematic model of eight degree of freedom is given under the combined slip condition, and then Kalman filter is obtained by the usage of DSP Builder of MATLAB/Simulink...
