摘要
磁轴承系统是一种复杂系统,可应用于航天器姿态控制系统,而数字控制是其发展趋势,采用一体化仿真、设计和实现平台,可以促进数字控制器在磁轴承领域的应用。为了解决磁轴承数字控制器快速实现的问题,在对磁轴承建模分析的基础上,基于xPC快速原型体系,以工控机为目标机,采用双机模式,在MATLAB环境下构建了一体化数字控制平台,并通过运行实验,实现了转子的稳定悬浮和高速旋转,验证了磁轴承控制算法的有效性。这种快速原型化方法可推广应用到其它复杂控制系统。
Magnetic bearing is a kind of complex system used in attitude control system of spacecraft, and the trend is to use digital controller. Adopting an integrative platform for simulation, design and implementation can promote the application of digital controller in magnetic bearing. In order to realize rapidly the digital controller of magnetic bearing, firstly, the model of magnetic bearing is analyzed. Secondly, an integrative platform of digit control based on xPC - rapid prototyping framework is built. The platform under MATLAB uses host PC and target PC which are industrial PC plugged data acquisition devices. Finally, the control arithmetic of magnetic bearing is proved effectively by the experiment results, the rotor can be suspended steadily and rotates at a high speed. The method can be used as guidelines for other complex control system.
