| Abstract: | ased on the study of the characteristics of servo brushless DC motor(BLDCM), a new control method is proposed in this paper. In this method the torque ripples caused by field distortion and inverter commutating can be minimized by using instantaneous torque control and overlay commutation. Applying the above-mention method to AC servo systems, we contruct an all digital system with INTEL single chip microprocessor 8098 as main control unit, and current adaptive PWM GTR inverter as power supply. Together with other hardware and deliberately designed software the system can run alternatively in the speed servo mode or position servo mode. |
