[0039] In the following, with reference to the accompanying drawings, the present invention will be described in detail by taking the process control of the liquid level of the four-tank tank as an example.
[0040] Such as figure 1 Shown is the flow chart of the distributed state feedback control method of the present invention, in which the continuous time process model of the four-capacity water tank is as follows:
[0041]
[0042]
[0043]
[0044]
[0045]
[0046]
[0047] Where h i Indicates the height of the liquid level of the water tank i, Represents the level derivative of the water tank i, v i Represents the speed of water pump i, Represents the derivative of the speed of the water pump i, u i Represents the speed control signal of water pump i, a i Indicates the cross-sectional area of the outlet of the water tank i, A i Represents the cross-sectional area of the water tank i, g represents the acceleration of gravity, γ i Indicates the ratio of the diversion of p...
