【摘要】：为使馈能悬架在一定范围内实现半主动控制,基于混合控制策略,确定了电机电磁阻尼力的控制算法.探讨了电机不同电磁阻尼力对悬架性能的影响及馈能悬架实现半主动控制的条件.在此基础上,以整车舒适性为目标,采用粒子群优化算法确定了电机阻尼力控制参数,并设计了直接电流控制器,使直线电机产生所需的电磁阻尼力.最后,对采用基于混合控制策略的馈能悬架进行了随机路面激励下的仿真分析.结果表明,优化的电机阻尼力控制参数能使馈能悬架实现半主动控制,显著改善馈能悬架的舒适性和平顺性,并能回收悬架部分振动能量.
[Abstract]:In order to realize semi-active control of the energy-fed suspension in a certain range, the control algorithm of the electromagnetic damping force of the motor is determined based on the hybrid control strategy. The effect of different electromagnetic damping forces on the suspension performance and the conditions of semi-active control of the suspension with feed energy are discussed. On this basis, aiming at vehicle comfort, the parameters of motor damping force control are determined by particle swarm optimization (PSO) algorithm, and the direct current controller is designed to generate the required electromagnetic damping force for linear motor. Finally, the simulation analysis of the energy-fed suspension based on hybrid control strategy is carried out under random road excitation. The results show that the optimized control parameters of motor damping force can make the feed suspension achieve semi-active control, improve the comfort and comfort of the suspension, and recover part of the vibration energy of the suspension.
