Research And Design Of Switched Reluctance Motor Speed ​​control System Based On Dsp

SRD is one new-style drive system made up of SRM,modern electronical technique,control technique. Because of its well performance, it becomes one of hotspots in electric drive of the time. Seizing opportunity to develop applied and cheap SRD is important for us to push the progress of electric drive and shorten the difference with advanced level in the world.In this thesis, the topic is to design and come true digital SRD controller. On the basis of generally and deeply summarizing some documents, research and discuss to SRD controller spreads. We analyzes the basic electromagnetism relation,run-mode and characteristic of SRM, and gets torque analytic formula in perfect condition, introduces the specialty and application of special digital signal processor - TMS320F240, then designs SRD hardware flat roof in the core of TMS320F240, and develops corresponding software. We uses adaptive fuzzy intelligent control strategy to increase the torque density,avoid current peaks,enhance robusticity and adaptive ability of controller by on-line parameter identification and correcting control parameters on time and match proper current loop, so torque-ripple is minished and high performanc-control of SRM is got. At last, the dynamic simulation to the system is done in MATLAB/SIMULINK, then analysis and study are given to this control scheme with simulation curves.
