Embodiment 1

[0065] Figure 4 This is a schematic diagram of the structure of the servo control MBD development platform provided by the embodiment of the present invention. like Figure 4 As shown, the servo control MBD development platform provided by the embodiment of the present invention includes: a real-time simulator, a servo motor, and a research and development type servo driver.

[0066] Figure 4 The medium-developed driver is directly connected to the 220V AC power grid, and the rectification and inverter functions are realized through the "AC-DC-AC" circuit. In this embodiment, a three-phase bridge circuit is used for the DC-to-AC inverter, see Figure 5 . The six IGBTs of the three-phase bridge arm are respectively controlled by PWM, which is the servo control interface opened by the platform.

[0067] The feedback signals of the servo system include the encoder feedback motor angle and magnetic pole positioning signal of the servo motor, the current signal of the Hall s...

Abstract

The invention relates to the software exploitation technology field and provides a servo control MBD exploitation platform. The servo control MBD exploitation platform adopts a host-target machine structure and comprises a real-time simulator, a servo motor and a research and development type driver. The real-time simulator outputs a PWM signal with a dead zone setting function through a motor control card. And then, a three-phase bridge-type inverter circuit on the research and development type driver is used to drive the servo motor to rotate. Simultaneously, incremental code disc signals are collected and a closed-loop control circuit is formed. Through applying a reverse moment load to a dragged load simulation motor, the on-load work characteristic of an alternating current servo motor is verified.

Description

technical field [0001] The invention relates to the field of software development, in particular to a servo-controlled MBD development platform. Background technique [0002] The mainstream method of the existing servo controller development is based on the DSP development board, and the user directly writes the C code manually to design the servo controller software. like figure 1 shown. [0003] For servo control development, in addition to the mainstream DSP code handwriting development, there are also some development methods based on embedded computer + DSP control card in recent years (Appendix 2). Compared with the direct DSP control method, this method increases the high-performance CPU card to participate in the calculation of the servo control algorithm, and improves the overall computing capability of the platform. like figure 2 shown. [0004] The existing higher-end motor servo control systems usually use DSP as the core processor, and are basically implem...
