Problems solved by technology
The main defect is that the real controlled objects in the industrial field, such as ships and boilers, etc., due to safety considerations, the control and debugging can only be fine-tuned, and can not be tested at will
At the same time, most of the transformation of the control system in the laboratory environment is aimed at the transformation of the hardware, which causes limitations in the system design and greatly limits the flexibility of the design

The invention discloses a semi-physical simulation control test platform and a test method thereof. The test platform comprises a laboratory controller I, a computer and mathematical software on the computer, and a virtual controlled object obtained by modeling a real controlled object on an industrial site via the mathematical software. A control parameter of the controller I can be repeatedly adjusted for optimization on the controller I when the controller I performs simulation control on the virtual controlled object through the computer; the optimized control parameter can be provided fora site controller II for controlling the real controlled object on the industrial site; an entity digital hybridization system is further designed; the mode that the traditional design is based on pure hardware transformation is changed; and a test method for adjusting parameters of the controllers in real time and sending the parameters of the controllers back to an actual controller for controlling is implemented on the basis of the above contents. The security problem caused by direct control and test of the industrial site and the very high cost of the test are effectively avoided.
Description
technical field [0001] The invention relates to a simulation control test platform and a test method, in particular to a semi-physical simulation control test platform and a test method which use an actual controller to control a virtual controlled object to simulate an industrial site. Background technique [0002] In today's society, the increasingly fierce market competition has put forward higher requirements and challenges for the time to market of products and the speed of new product development. At present, the design of many control systems and electronic systems is either full hardware testing or full software simulation development. During the process, problems such as software code errors or unreliable hardware environment for software code operation often occur. [0003] The prior technology integrated control test box has been used as an actual controller in the industrial field. Based on OPC technology, the online version of MCGS and MATLAB communication compl...
