【摘要】 为了提高钢板无接触传输磁悬浮系统的鲁棒性和品质指标 ,本文引入H∞ 控制。首先分析了由气隙、悬浮体质量和电磁系统特性参数变化的误差模型 ,在此基础上 ,提出H∞ 控制器的设计方法。将H∞ 控制与传统PID控制进行了比较研究。更多还原

【Abstract】 In order to improve the robustness and performance of a EMS control system for steel plate conveyance, H ∞ control is introduced.In this paper,the perturbed model caused by airgap,suspended mass and magnetic characteristic deviations is investigated.How to design H ∞ control for steel plate EMS is studied. H ∞ control in steel plate EMS system is compared with that of traditional PID control.更多还原
