【Abstract】 In this paper the author points out the fact that in a slip frequency type vector control system when the resistance values of the motor’s stator and rotor vary with running temperature,its torque control perfermance will also vary. Therefore,according to modern control theory,the author considers that by means of flux observer, the torque control performance of vector control system will get better. Then the author fulfils such tasks as modelling,steady-state analysis and digital simulation of new-type vector control system, and finally tests this solution’s effect.更多还原
