| 摘 要： | 针对混合磁悬浮轴承,提出一种对磁悬浮轴承转子模糊控制的策略.结合电磁绕组工作原理,采用自感式位移自检测系统代替专门的位移传感器,构成无传感器自检测磁悬浮控制系统,通过模糊PID(proportional,integral and differential)控制器对系统进行控制,并建立了控制系统的数学模型.分析模糊PID控制器整定参数的模糊规则及模糊控制原理,对系统进行了模糊仿真.仿真结果表明:采用模糊PID控制混合磁悬浮轴承系统具有响应快、抗干扰能力强的动、静态性能.

| Abstract: | This paper puts forward a fuzzy control strategy for the rotor of magnetic suspension bearing.Instead of the displacement sensor,it combines the operating principle of electromagnetic winding with the self-{inductance} displacement self-sensing system.It consists of self-sensing maglev control system without sensor.The mathematical model of control system is established by the fuzzy PID control system for fuzzy control.With the analysis of the fuzzy rule and fuzzy control principle of fuzzy PID controller s... |
