Design and Research on Time-overlapping Gearshift Systems for AMTs
摘要
Abstract
In order to shorten the power interruption duration of AMT,a time-overlapping gearshift system was developed based on the electromagnetic linear actuators. The structures and working principles of the electromagnetic linear actuators were presented. A coupling system model including mechanical,electric circuit and magnetic circuit subsystems was built. The characteristics of the actuator were analyzed by experiments. The time-overlapping control strategy was presented,and the position compound controller was designed based on the two-degree-of-freedom control principle. The simulation and experimental results show that the proposed position cascade controller achieves good response and disturbance rejection performance. When the speed difference is as 500 r/min and the synchronized equivalent inertia is as 0.01 kg·m2, gear-change from 2nd to 3rd,the time is about 130 ms,the time-overlapping control method has about 20ms time-saving,and the total time is reduced by more than 15%.关键词
