SoC-based motor hardware-in-loop simulation method

Abstract

The invention discloses a motor hardware-in-loop simulation method based on SoC, and the method comprises the following specific steps: A, building a closed-loop control simulation model of a DC motor in Simulink, adjusting the parameters of a controller in the simulation model, and converting a motor model in the simulation model into a model compatible with HDL after the expected steady-state control precision and dynamic response speed are reached; step B, calling an HDL Coder toolkit to convert the direct current motor model with parameters into Verilog HDL codes, packaging the direct current motor model into an IP core of an AXI interface, and integrating the IP core at a PL end of the SoC; and step C, deploying a motor model IP core at a PL side and a PS side to construct a control algorithm, and carrying out HIL simulation on the direct current motor. According to the method, early algorithm design and test can be conveniently carried out on the motor controller, a real motor is not needed, the cost is low, and the research and development period is short.

Description

Technical field [0001] The present invention relates to the field of servo drive control technology, specifically a soC-based motor hardware-in-the-loop simulation method. Background [0002] As a power output component, the motor plays a very important role in the process of modern industrialization. Research on the control, testing and practical application of motors has been a major concern. Before the actual equipment application of the motor control system, it is often necessary to carry out a large number of tests, and the traditional test method is to build a complete set of prototype equipment platform containing controllers, motors and loads, etc., and conduct relevant experiments on this platform. This method is costly, has a long execution cycle, poor operability and repeatability, and there is a certain test hazard in high-power motor control applications. With the development of digital computers, simulation applications based on system-level models are beginning to ...
