Problems solved by technology

[0004] At present, the hardware-in-the-loop simulation test platform that appears in the scientific research field or on the market can only test one function of the controller when testing. When other functions of the controller need to be tested, hardware replacement or software modification is required. Re-development, complicated test operation process
[0005] Therefore, the existing hardware-in-the-loop simulation test platform has a single test function, poor scalability, and complicated test operations, which has caused a lot of inconvenience to users.

Description

technical field [0001] The invention relates to the technical field of data simulation, in particular to a semi-physical simulation test method, device and system. Background technique [0002] The test of the robot controller mainly includes the test of the controller core software (common black box and white box tests such as function, performance, code quality, etc.) and the test of the external interface (EtherCAT, RS232, GPIO, etc.). The robot controller is tested under real working conditions, and it is necessary to test its various functions and performance indicators in actual operation. [0003] The semi-physical simulation platform is a test platform that connects the controller (real object) and the controlled object (simulation model) together for testing. In the experiment based on hardware-in-the-loop simulation, the dynamic characteristics, static characteristics and nonlinear factors of the controller can be truly reflected, so it is a simulation experiment ...
