Abstract

The invention discloses a control system and method of a series DC motor. The control system comprises a communication unit, a speed acquisition unit, a control unit and a driving unit, wherein the communication unit is used for sending received control information to the control unit of the control system and is also used for sending the control information and state information of a DC motor corresponding to the control system to at least one control system which is connected in series, the speed acquisition unit is connected with the DC motor and is used for acquiring rotational speed information of the DC motor, the rotational speed information comprises a pulse output parameter of the DC motor, the control unit is used for generating a rotational speed regulation parameter according to the control information and the rotational speed information, and the driving unit is connected with the control unit and the DC motor and is used for adjusting a driving voltage according to the rotational speed regulation parameter. By the control system, the technical problem of large resource occupancy when a plurality of motors are needed to be controlled by the motor control system is solved.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a control system and method for a series DC motor. Background technique [0002] Motor speed control technology is widely used in the field of automation control. It can be used on the control units of actuators in various digital control systems to accurately control the speed of various intelligent machines. Among them, the intelligent machines include robots, AGV trolleys Wait. However, in the existing motor speed control system, multiple motors need to be controlled. For example, multiple motors need to be controlled in a robot system. When controlling multiple motors (such as DC motors), the rotational speeds of multiple motors need to be collected Information, and send multiple control information to the corresponding motor according to the speed information, the controller of the motor control system needs to send and receive multiple sets of motor information at the same tim...
