In order to improve the brake performance of a dual independent electric drive tracked vehicle,a dynamic model for braking situation was ***,a sliding model controller(SMC)with an auxiliary system was designed to control the slip and its effectiveness was proved.A hardware-in-loop simulation through MATLAB/XPC was compared with the normal SMC and normal integral sliding mode controller(ISMC),the results show that SMC with the auxiliary system has a better performance:a smaller overshoot and steady state *** disturbance is suppressed *** the initial speed of ***/h,the brake distance was shortened by 3.4%and 6.8%compared with the other two methods,***,initial speeds of ***/h tests was carried out on a flat soil *** with a no-control brake,the displacement was shortened by *** demonstrates the effectiveness of the slip-control *** the same situation,the error between the simulation and test is 18.1%,which validates the accuracy of models.

High-speed Brushless DC Motors(BLDCMs)usually adopt a sensorless control strategy and operate in three-phase six-state drive ***,the sampling errors of the rotor position and the driving method increase the Internal Power Angle(IPA),resulting in a decrease in the efficiency of the *** IPA reduction strategies are either sensitive to motor parameters,or ignore diode freewheeling during the commutation process,or require additional current *** this paper,a new strategy to reduce the IPA is ***,a Zero-Crossing Point(ZCP)detection method for the back-EMF without filter is proposed to reduce the sampling errors of the rotor ***,the relationship between the non-energized terminal voltage and the ZCP of the corresponding back-EMF is *** non-energized terminal voltage that has completed the diode freewheeling is divided into two triangles by half of the bus *** the IPA is suppressed,the areas of the two triangles are ***,an advanced angle for reducing the IPA is obtained through a PI regulator which can eliminate the deviation between the two ***,both a simulation model and an experimental circuit are built to verify the proposed control strategy.

Inertia Matching During Dynamic Simulation of Vehicle drive System on Test Bench

引用

Journal of Beijing Institute of Technology 2004年第2期13卷 197-201页

作者：宋强孙逢春郑慕侨顾进超 School of Mechanical and Vehicular Engineering Beijing Institute of Technology Beijing100081 China

Framework and basic parameters of a test bench for motor drive system of electric vehicle (EV) are illuminated. Two kinds of electric drive models, one was for the electric vehicle drived on real road, the other was for that on test bench, are put forward. Then, dynamic analysis of these models is made in detail. Inertia matching method of the test bench is researched and some useful formulas and graphs are brought forward. The experiment of an electric bus is introduced in order to explain the usage of this inertia matching method.
