Abstract

The invention relates to an online parameter adjustment method based on digital communication. The method comprises the following steps: a controller and a simulator communicate through a JTAG interface so as to debug a program in a DSP; the controller and the simulator communicate through the JTAG interface to program the debugged program into a FLASH chip of the controller; a host computer reads currently used control parameters through a digital interface, and if performance requirements are satisfied, the control parameters are not modified; if the performance requirements are not satisfied, control parameters to be modified are input, and the control parameters to be modified are sent to the controller through the digital interface; the controller receives the control parameters to be modified sent by the host computer through the digital interface and stores the control parameters to be modified in an EEPROM chip; and the controller, through reading the control parameters stored in the EEPROM chip, updates system control parameters so as to perform subsequent motion to realize control of a servo system. The method realizes online parameter adjustment of the servo system, greatly simplifies the debugging process and improves the work efficiency.

Description

technical field [0001] The invention relates to the technical field of servo control, in particular to an online parameter adjustment system and method based on digital communication. Background technique [0002] Generally, the servo system debugs the program in the simulation state, and burns the program into the FLASH memory after the debugging is completed. The servo system debugs and burns the program through the JTAG interface of the emulator, and downloads the program to the FLASH memory of the controller when burning the program. The servo system needs to meet the requirements of various environments. For example, the control parameters at room temperature may not meet the performance of the control system at high and low temperatures, so it is necessary to modify the control parameters frequently. When modifying the control parameters, you can only reprogram the program to In FLASH, therefore, frequent program programming is required, which affects the life of FLAS...
