【摘要】 目前国外在磁悬浮方面的研究工作主要集中在磁悬浮列车方面，德国和日本等国在这方面已经取得了重要进展，磁悬浮列车技术开始走向实用阶段。在我国，磁悬浮技术的研究从80年代初开始的，目前已掌握了磁悬浮列车技术。另外，在磁力轴承、磁悬浮天平、磁悬浮高速电机及相关技术的应用也都得到了发展，国外已经开发出这类高技术产品并已经进入市场。 本文对四点吸引式磁悬浮实验系统进行了设计和分析，对磁悬浮系统的各个组成部分及其原理进行了详细的说明。建立了磁悬浮系统的数学模型，并对数学模型在平衡点附近进行了线性化，得到了系统的状态方程和传递函数。在此基础上，分析了系统的能控性和能观性，对磁悬浮系统设计了线性状态反馈控制器、PID控制器、P-FUZZY-PI控制器和平衡法控制器。分别给出各种控制器的设计思想、方法和设计步骤。并把几种控制器的控制性能进行了仿真，得出了各种控制器的性能特点，分析了各种控制器在实际系统中的可行性，在实验的基础上，把平衡法控制器应用于磁悬浮系统，并给㈩了平衡法控制器的实现和控制算法。更多还原

【Abstract】 Up to present, abroad research on magnetic suspension mostly centralizes on EMS maglev vehicle. Some countries, such as Germany and Japan, have made great strides. EMS maglev vehicle technology began to tend towards practical application phase. In our country, research on magnetic suspension has begun since earlier 1980’s. In addition, magnetic bearing, magnetic balance, magnetically levitated electric machines, and correlative technology applications have developed. High tech productions in foreign nations have already exploited and entered market.In this paper, a four-point attraction magnetic suspension system is designed and analyzed, the principle of each part of the magnetic suspension system is described in detail. The mathematic model of magnetic system is set up. By linearizing the mathematic model in the equilibrium point, the author gets the state function and transfer function of the system. On the basis of the mathematic model, the controllability and observeability are analyzed, several kinds of controller including linear states feedback controller, PID controller, P-FUZZY-PI controller, balance method controller are designed for the system. Some method and design steps of the controller are given. Simulations are made to the controllers, features and performance of each controller are gotten. Feasibility of each controller is analyzed. On the basis of experiment, the author proposes that to apply the balance method controller to the magnetic suspension system. At last, the application method and the control algorithm of the balance method controller are given.更多还原
