The fuzzy-P ID strategy and the des gn process of fuzzy-P ID contro lle r w e re d sse rtated. A fuzzy-P ID contro ller w as des gned. T he EHPS sy stem model w as establ shed n AM ES m andM ATLAB / S m ul nk to m ake sm ulat ons w th track- ng o f ob jec t current, rota ry speed charac ter o f BLDCM and sm ooth steer ng o f EH PS system. T he smu la t on results nd ca te that the BLDCM contro lled by fuzzy-P ID strategy has a be tter sta t c and dynam c cha racte r st cs than the BLDCM contro lled by P ID strategy, so the EHPS system has a be tter smoo th steer ng character st c.
