磁悬浮球系统是一个复杂的系统，其研究涉及控制理论、电磁场理论、电力
电子技术、数字信号处理以及计算机科学等众多领域。磁悬浮球的控制器和功率
放大器在系统中起着决定性的作用，它们的性能不但决定了磁悬浮球能否稳定悬
浮，而且直接影响到磁悬浮球的动态性能。本文主要针对磁悬浮球系统的控制器
和功率放大器进行分析和研究。(The magnetic levitation ball system is a complex system, which involves control theory, electromagnetic theory and electric power
Electronic technology, digital signal processing, computer science and many other fields. Controller and power of magnetic levitation ball
Amplifiers play a decisive role in the system, and their performance not only determines whether the maglev ball can be suspended stably
Floating, and also directly affect the dynamic performance of magnetic levitation ball. This paper mainly focuses on the controller of magnetic levitation ball system
And power amplifier are analyzed and studied.)
