Abstract

The invention provides an FPGA-based shakeless drive control system of a stepping motor and a control method based on the system, relating to the field of stepping motor control and solving the problem that a traditional stepping motor control system cannot avoid poor timing control accuracy during driving, shortage of external communication interfaces and structure complexity of an electric system. According to the system disclosed by the invention, an upper computer carries out data interaction with an FPGA controller through a serial communication bus; the FPGA controller outputs a pulse signal, a direction signal, an enable signal and a mode signal to a digital signal isolation module; a control signal output end of the digital signal isolation module is connected with a control signal input end of a stepping motor drive module; the stepping motor drive module drives an external motor; a power isolation module is respectively connected with the FPGA controller, the digital signal isolation module and the stepping motor drive module. Through using FPGA and integrating a stepping motor power drive chip, the complexity of the electric structure of the stepping motor drive control system can be reduced largely and moreover multi-communication-mode expansion capability is also considered.

Description

technical field [0001] The invention relates to the field of stepping motor control. Background technique [0002] Stepping motor is a commonly used electromechanical component. It controls the phase winding current through electric pulse signal, and then completes the fixed-angle rotation control. Compared with other types of motors, stepping motor has many advantages, such as easier to realize Open-loop precise control and no accumulated error, etc., so stepper motors are widely used in various fields, and most of them use single-chip microcomputers as the control core control systems. This type of control system often uses software and interrupt services to control the timing of the stepper motor drive logic, which has the disadvantages of consuming more CPU resources, insufficient external communication interfaces, and poor timing control accuracy. Therefore, some scholars propose to combine the single-chip microcomputer and CPLD or the combination of single-chip microc...
