Embodiment 1
[0046] The following examples are given to illustrate the above-mentioned integrated multi-model control method based on PID, and a continuous stirred reactor system (CSTR) is simulated and analyzed.
[0047]
[0048] where C A (mol / l) is the reaction concentration, the input variable is u(min -1 ). C in the equation Ai (1.0mol / l) is the feed concentration, k=0.028min -1 is the rate constant. This system is highly nonlinear, and a single linear controller cannot meet the requirements.
[0049] Adopt the self-balanced multi-model decomposition algorithm of the present invention to carry out multi-model decomposition and control to the CSTR system, and the specific steps are as follows:
[0050] S0. Using the dichotomy method based on the gap metric to grid the CSTR system to obtain 19 grid points. And calculate the linearization model, and use the calculation formula (1) of gap metric to calculate the gap distance between the linearization models;
[0051] S1. Select ...
