摘要:
研究了变速器试验台采用电机模拟机械飞轮惯量的实现方法.以在相同转矩作用下机械惯量系统和电惯量系统的转速变化一致为控制目标,提出了电惯量角加速度控制法.以电枢电流和角速度为输入,设计Luenberger观测器来估计角加速度,并在观测器中加入滤波器模型,同时反馈增益根据转速变化的大小自适应变化来平衡噪声抑制和响应速度之间的矛盾.采用Matlab/Simulink建立了变速器试验台及惯量电模拟系统的仿真模型,研究了电惯量在变速器升档过程中的作用.结果表明,转速误差的峰值小于1rad/s时,观测器可以快速、准确实现角加速度的估计,且噪声抑制能力强,以此为基础的惯量电模拟方法可以有效取代机械飞轮.
Abstract:
Realization method of emulating mechanical flywheel inertia by electrical motor for transmission test rig was researched. To make the speed variation of electrical motor correspond with the mechanical inertia under the same torque was token as a control target, and the electrical inertia angular acceleration control method was proposed. Luenberger observer with the armature current and angular velocity as input was designed to estimate angular acceleration. The filter model was integrated into the observer, and the feedback gain was adapted according to the change rate of the speed, thus a compromise between the noise attenuation and response speed was achieved. The simulation model of transmission test rig and inertia electrical emulation system was developed by Matlab/Simulink. The up-gear shift process was analyzed. The results indicate that the error of angular velocity is less than 1 rad/s. The observer can estimate the angular acceleration accurately and attenuate noise robustly. On this basis, the proposed inertia electrical emulation can replace the mechanical flywheel effectively.
