In view of the abstract content of the Power Control Principle and Technology course and the lack of students'intuitive understanding of practical engineering control cases,a virtual experiment system of magnetic levitation ball based on semi-physical simulation is designed and developed,and the key technologies of the realization of the virtual experiment system are introduced in detail.The simulation model of magnetic levitation ball,the realization of customized target hardware and software,and the communication method between virtual magnetic levitation ball and embedded target are given.Through the designed virtual experiment system,various open experiments can be carried out,such as system modeling,PID cascade suspension control,embedded controller design,etc.,to make up for the restrictions brought by the physical experiment device,so as to achieve the purpose of teaching through lively activities and improving the teaching effect.
