【摘要】 本文提出了应用于直线感应电机(LinearInductionMotor:LIM)的纯电制动,考虑了LIM与RIM纯电制动的区别——边端效应及转差频率大等,在实验室直线电机牵引传动实验平台上通过Matlab/Simulink仿真与实验证明了纯电制动的可行性,并在规定的距离内进行定点停车实验验证。考虑到直线电机地铁对乘坐舒适度的要求,引入了停车前的减减速度控制,广州地铁四号线的仿真验证了提出控制方法的有效性,提高了停车时乘坐舒适度。更多还原

【Abstract】 This paper proposes pure electric brake applied in the LIM.Compared with rotary motor, the linear induction motor possesses such feature as the end effect and large slip frequency.In this paper,the proposed pure electric brake strategy is realized through simulation first,subsequently the experimental results verify the practicability of pure electric brake through stopping accuracy test.Finally,for better riding comfort,jerk control is introduced in the simulation of Guangzhou Subway Line 4,and which has also been testified effective.更多还原
