Embodiment 1

[0025] Example 1 as figure 1 As shown, an integrated multi-axis synchronous motion control system is mainly composed of a feedback sampling module and a main control module. The main control module is set on the main control circuit board, and the feedback sampling module is set on the amplification circuit board. The feedback sampling module samples the running current and running position of the multi-axis servo motor, and the sampling result is input into the main control module, which is used to realize multi-axis synchronous current loop control, multi-axis timing synchronous scheduling and multi-axis response synchronous control.

[0033] Among them, multi-axis synchronous current loop control includes single-axis high-speed current loop control and multi-axis parallel pipeline synchronous current loop scheduling.

[0034] The single-axis high-speed current loop control adopts the space vector control method with PI regulator combined with parallel computing and serial computing. This method can maximize the computing speed of the controller and save computing resources, including:

[0035] Single-axis signal preprocessing stages, such as image 3 As shown, the entire current loop control sequence occupies the first-third time period (t 1 -t 3 ), including feedforward current reading, speed loop generated current reading, feedback current sampling, encoder position samp...
