Embodiment 1
[0140] Taking the injection molding stage and pressure holding stage in the injection molding process as an example, the injection molding process is a typical multi-stage chemical process, and the adjustment method is to control the valve opening of the proportional valve and the control of the pressure holding pressure.
[0141] The present invention is achieved through the following technical solutions:
[0142] A new type of predictive function control method optimized for chemical process genetic algorithm, including the following steps:
[0143] Step 1. For different stages in the chemical process, establish a switching system model based on the state space model of the controlled object, specifically:
[0144] 1.1 Construct a new multi-stage chemical process with disturbance system model:
[0145]
[0146] Among them, k represents the current time, x i (k)∈R n , u i (k)∈R 1 ,y i (k)∈R 1 Respectively represent the state, output and input of the batch process at...
