中文摘要：
将直线电机作为汽车主动悬架的作动器,能实现悬架的主动减振。建立整车主动悬架的动力学模型和直线电机的数学模型,输入三相交流电,测试直线电机的电磁力,仿真与试验的结果较为一致,验证了电机数学模型的正确性。基于整车姿态协调控制原理,结合模糊控制理论和电流滞环控制策略,研究了包含直线电机作动器的车辆主动悬架的动态响应。结果表明,该控制策略可行,且控制系统能有效改善车辆舒适性和行驶安全性,车身姿态也得到有效控制。
英文摘要：
A linear motor was used as a vehicle active suspension actuator in order to realize active vibration reduction. A dynamics model of vehicle active suspension and a mathematical model for the linear motor were established. The three-phase AC input was used for the linear motor to test electromagnetic force.The good agreement between simulation and test results verifies the correctness of the model. Finally; fuzzy control theory and current hysteresis control strategy were combined based on vehicle coordinated attitude control principles to study the dynamic response of active suspension with linear motor. The results show that the control strategy is feasible, and the proposed vehicle attitude control system can effectively improve ride comfort and driving safety.
