Abstract

The invention relates to a double-motor synchronous servo drive device based on DSP. The device comprises a DSP system control module and a motor power drive module which are connected into a whole through a control interface; a digital signal processor of the DSP system control module is connected with a host computer or a control system through a CAN bus interface and an RS232 interface so as to realize real-time communication; the digital signal processor is synchronously connected with a motor code disc through a code disc interface so as to carry out closed-loop control on a motor; a switch power circuit of the motor power drive module supplies power for the motor power drive module through a power interface; an overcurrent protection circuit and a power drive circuit are communicated with the digital signal processor of the DSP system control module through a control interface; and the output of the power drive circuit is connected with the overcurrent protection circuit and is connected with a direct current motor. The double-motor synchronous servo drive device is used for a double-wheel differential type service robot and motor drive and control with synchronous requirement process in order that double motors synchronously drive and control, thereby effectively improving the capacity for synchronous coordinated movement and control precision of double motors.

Description

technical field [0001] The invention relates to the control equipment of electromechanical integration and servo transmission device, specifically a DSP-based dual-motor synchronous servo drive device, which is suitable for motion control products such as mobile robots that require motor synchronous drive. Background technique [0002] Traditional dual-motor motion control has been implemented as a combination of motion controllers and servo drives. Generally, it is composed of a motion controller and two servo drive products. Such a control method has many application components in mobile robot products, which is not conducive to miniaturization and synchronous control. High-precision motor synchronous motion control has high real-time requirements and a large amount of calculation. It is difficult for ordinary single-chip microcomputers and general CPUs to complete, and the motion controller cannot be combined with servo drive products. [0003] In recent years, with the...
