摘要
A method and device for evaluating the performance of an industrial control loop based on full loop reconstruction simulations. The method comprises: performing reconstruction simulation on control modules one by one except a controlled object in the loop, and judging the correctness of the reconstructed modules; establishing a mathematical model of the object, connecting the mathematical model to the reconstructed modules to complete reconstruction of the entire loop, and optimizing the mathematical model of the object to obtain an optimized model of the object; adjusting parameters of the modules according to a control performance index, and performing simulation calculation on the reconstructed loop using the parameters to obtain an ideal value of the reconstructed performance control index for evaluating the performance of the loop. The loop is reconstructed, the influence of the modules, a PID controller, a filter, a piece-wise linear function and a deadband, on the performance is evaluated.
