Embodiment Construction
[0035] Sliding mode control method of methanol autothermal reforming hydrogen production process to respond to the flow u of methanol aqueous solution 1 and the flow rate u of another reaction raw material air 2 As the manipulated variables, the hydrogen output y and the reforming temperature T are the controlled variables.
[0036] A sliding mode control method for the hydrogen production process of methanol autothermal reforming, which is characterized in that the sliding mode controller is used according to the expected hydrogen production y d , the actual hydrogen production y and the change rate of the actual hydrogen production x 2 To manipulate the flow rate u of the reaction raw material methanol aqueous solution 1 , while using a variable ratio controller with a constraint on the reforming temperature T to manipulate the flow rate u of the other reaction raw material air 2 , the specific steps include:
[0037] In the methanol aqueous solution, the molar ratio of ...
