【摘要】 由于轨道不平顺变化会对悬浮系统有影响,选择适合于单电磁铁悬浮系统的PID控制仿真方法是悬浮控制系统设计中的一个很重要的问题。基于单电磁铁悬浮系统的数学模型,提出了3种PID控制仿真方法。利用Matlab/Simulink中的工具箱,通过仿真验证了3种PID控制系统的可行性。结果表明:与方法 1和方法 2相比,基于S函数的方法 3对轨道低频振动能实现有效地跟踪,且对轨道高频振动具有较强的抑制能力。该研究成果为解决单电磁铁悬浮系统的轨道不平顺问题提供了一种较好的仿真方法。更多还原

【Abstract】 Due to the impact of the track irregularity on suspension system,selecting the suitably PID control simulation method for single electromagnet levitation system is a very important problem in the design of the suspension control system. In this paper,the mathematical model of single magnet suspension system is based on PID control,and this paper puts forward three kinds of simulation methods. By using of Simulink toolbox in Matlab,the simulation verifies the feasibility of three kinds of PID control system,and the simulation results show that the third simulation method based on S function can more effectively realize the low frequency vibration of track,and have stronger suppression ability to the high frequency vibration of track,compared to the first simulation method and the second one. In this paper,a better simulation method is provided for solving the single electromagnet levitation system of track irregularity problem.更多还原
