| Abstract: | The basic theory of variable structure sliding mode control (VSSMC) is discussed.The model of VSSMC of Brushless DC motor is designed and verified by emulation,and directed to the form of state equation.The line of variable structure sliding mode is selected according to proportional control run to zero with fixed speed.The exsisting conditions of variable structure sliding mode are given.The design is used in a BLDCM timing system.The simulation and experiment is finished.Compare with the traditional PI control,the VSS is proved that the system performance is improved. |
