Problems solved by technology

When applied to multi-axis servo control, the single-processor MCU takes a long time to execute and cannot process multi-axis servo control in parallel, so the real-time control and algorithm accuracy cannot be guaranteed
In summary, both of the above two technical solutions have the problem of unreasonable division of software and hardware, and it is difficult to meet the application requirements of multi-axis servo motor drive systems

Abstract

The invention discloses a multi-axis servo drive controller based on a multi-processor on-chip system. In a single FPGA chip, a network communication module, at least one motor drive control module, at least one on-chip shared RAM, EPCS controller, on-chip RAM, main processor, etc. are integrated to realize independent and synchronous drive control of multi-axis AC servo motors; Each motor drive control module includes current loop servo control IP core, slave processor, MUTEX core and on-chip RAM, software and hardware cooperate to complete the position, speed and current closed-loop control of single-axis AC servo motor. The whole system has the characteristics of simple structure, strong real-time performance, fast response, and convenient expansion. It has broad application space in multi-axis servo applications in electric vehicles, industrial automation, and national defense industries.

Description

technical field [0001] The invention relates to a servo drive controller, in particular to a multi-axis servo drive controller based on a multiprocessor on-chip system, and belongs to the technical field of motor drive control. Background technique [0002] In the fields of electric vehicles, industrial automation, and national defense, the permanent magnet AC servo system occupies a pivotal position; many applications usually need to simultaneously drive and control multi-axis servo mechanisms in a very limited space, such as multi-joint manipulators and robots, multi-axis Linked CNC machine tools, exoskeleton systems, missile servos, mechanical phased array antennas and other equipment require precise drive control of many servo axes at the same time; the implementation of multi-axis servo drive controllers mainly includes DSP-based software implementation solutions and based on FPGA hardware implementation. Due to the serial execution of software codes and the limitation...
