摘要
针对普通线性化控制方法不能满足磁悬浮系统的全局稳定的问题,研究了基于非线性磁悬浮系统模型的精确反馈线性化控制算法设计方法。建立了磁悬浮系统非线性模型,利用状态反馈将系统精确线性化,然后通过极点配置,按照动态性能设计指标计算出控制参数,得到符合工程实践要求的反馈算法。仿真和实验证明了这种控制方法能够保证磁悬浮控制系统的动态特性,同时具有较好的抗干扰能力。
To the problem that common linear control method cannot ensure the global stabilization of maglev systems, the accurate feedback- tinearization control method based on maglev system models is designed. The nonlinear maglev system model is founded and the system is linearized by state feedback. According to dynamic performance, the control parameters are designed. The feedback control method is founded according with engineering demand. The simulation and experiment results show that this method can ensure the dynamic performance of maglev systems. The system ability of resisting disturbance is fine.
