Design Of Controller Based On Dual DSP For Bearingless Switched Reluctance Motor

The bearingless motor is one kind of novel, high performance motor integrating magnetism bearing and SRM. Not only does it get rid of the SRM rotational speed limit of the mechanical bearing, but it is also probable to reduce the vibration and the noise which are produced in the motor movement process. It has several merits of long life, less mechanical friction, need not lubrication etc., suiting to the high rotational speed and high power application.This dissertation introduces the basic structure, mathematical model, function mode and control method of the bearingless SRM. The main winding power converter and assistant winding power converter of the bearingless SRM control system and the bearingless SRM digital controller based on dual DSP(TMS320LF2407) has been designed, includes the dual DSP control circuit, the dual RAM communication circuit, the CPLD logic processing circuit, the A/D sampling circuit, the displacement examining circuit, the rotor position sensing circuit, the SCI serial communication circuit, the keyboard circuit and so on.For the bearingless SRM control method, the dissertation expatiates the software flow which has realized this method, conductes the experimental research, and finally gives partial experimental waveforms.
