Abstract
Control schemes of brushless DC motor are always achieved in the way of program,but the period of the project is long,and the process is complex because of hard work programming.While dSPACE is a software and hardware platform for the real-time control system based on Matlab/Simulink.It has no program,but excellent real-time performance and high reliability.The time of the development is short.On the basis of dSPACE BLDCM system,build the motors 3-phase back EMF based on S-function and implemented the speed closed-loop control of BLDCM in Matlab/Simulink.Then built the actual system on the dSPACE platform,and debuged the line parameter by ControlDesk.The experiment Result verified the superior performance of BLDCM and the reliability of the platform,which offers foundation for the design of more complex control algorithms.
