Abstract

The invention discloses a servocontrol system for an on-chip motor, which comprises a processing system, a system interface circuit and a motor driving system. The processing system is connected with the motor driving circuit through a system interface circuit, the motor driving system is connected with the motor, and the motor control instruction can be generated by the processing system and then can be sent to the motor driving system so as to drive and control the motor, the system interface circuit can achieve communication function with other peripheral devices simultaneously, and can transmit the status message of the motor which is collected by the motor driving system to the processing system. The control system can achieve the data control of various motor systems only through replacing the power MOS tube, and also achieve multi-channel control signal output.

Description

technical field [0001] The invention relates to a motor servo control system, in particular to a motor servo control system based on on-chip programmable technology (SOPC). Background technique [0002] At present, in the field of industrial control, various types of motor servo systems are put into use, and these different types of servo systems use different controllers. Therefore, once another type of motor servo system is used, a corresponding controller needs to be used, which will lead to an extension of the system development cycle and a significant increase in cost. Contents of the invention [0003] In order to overcome the deficiency that the same controller cannot be used in the prior art, the present invention provides an on-chip motor servo control system, only need to select the corresponding power amplifier MOS tube according to the actual power of the motor, to realize multi-channel parallelism for various types of motors control. [0004] The technical s...
