Embodiment 1
[0188] A reversible exothermic reaction exists in a plug flow tubular reactor In order to maximize the concentration of product B, the optimal control strategy of the coolant flow rate needs to be studied. Its mathematical model is as follows:
[0189]
[0190] where x 1 (t), x 2 (t) respectively represents the concentration of the standardized product B, temperature (K), and u(t) represents the normalized flow rate of the coolant.
[0191] The control room engineer divides the duration of this production process t f =5min, the required information of coolant flow rate 0≤u(t)≤0.5 is input into the information collection module of DCS. The DCS immediately starts to run the optimal control method of the self-adaptive optimal control node, and its running process is as follows: image 3 Shown as:
[0192] Step E1: Initialize the operation of module 2, set the initial control grid number p=16, and the initial guess value of the coolant flow rate control strategy Set co...
