摘要
针对燃料电池空压机目前存在的驱动和支承问题,提出一种箔片动压轴承和动力磁轴承一体化的气磁悬浮型空压机。基于空压机的结构组成,建立空压机磁悬浮支承力、气悬浮支承力以及空压机转子动力学数学模型;基于燃料电池空压机转子系统动力学模型的状态空间方程,设计抗干扰强的协同控制器,并对它进行了转速、驱动转矩、转子悬浮位移以及电磁调节力等关键物理量的仿真分析。结果表明:协同控制在响应、抗干扰以及鲁棒性方面的控制优于PID控制。基于协同控制和PID控制建立了控制实验平台,并对空压机转子的气磁悬浮进行分析,进一步验证了协同控制具有优良的控制效果和良好的控制性能。
Aiming at the current driving and support problems of fuel cell air compressors,an air-magnetic suspension type air compressor was proposed integrating foil dynamic pressure bearing and power magnetic bearing.Based on the structural composition of the air compressor,the mathematical models of the air compressor magnetic suspension support force,air suspension support force,and rotor dynamics air compressors were established.Based on the state space equation of the dynamic model of the fuel cell air compressor rotor system,a strong anti-interference collaborative controller was designed,and key physical parameters such as speed,driving torque,rotor suspension displacement,and electromagnetic regulating force were compared and simulated.The results show that collaborative control in response,anti-interference,and robustness are outperformed than PID control.A control experimental platform was established based on collaborative control and PID control,and the analysis was conducted on the air-magnetic suspension of the air compressor rotor,further the excellent control effect and control performance of collaborative control were verified.
