摘要
Abstract
In order to solve the problems of large step angle,low frequency oscillation and low control accuracy in stepper motor control,this research used field-programmable gate array(FPGA)as the mas-ter chip to achieve double closed-loop control on the current and speed of a two-phase hybrid stepping motor.By taking advantage of fast operation,good real-time performance and flexible programming of FPGA,multiple PWM control signals were generated synchronously via the digital comparator to reduce the step angle of the stepper motor as well as improve the performance of the servo system and the stable operation of the motor.The final test results show that the closed-loop drive technology helps to solve the related problems in the stepper motor control,and has good practical value.关键词
