Embodiment Construction

[0042] The steps of the two-level grid method of the present invention will be further described below in conjunction with the accompanying drawings. Refer to attached Figure 1-5 , Table 1-2.

[0043] Secondary grid method of the present invention, concrete steps are as follows:

[0044] Step 1. The offline preprocessing process of the two-level grid method, see the flow chart for details Figure 4

[0045] 1.1. Introduce multi-parameter quadratic programming into the control system, and divide the system state space into convex partitions. The schematic diagram of the state space is as follows Figure 4 shown, and calculate the control rate corresponding to each partition, and save it in the FG array.

[0046] 1.2, Calculate the synonymous partition. If the eigenvalues ​​of different partitions are the same, the color of the partitions is also the same, such as figure 2 shown.

[0047] 1.3. Construct a first-level hash table grid area polytope.

[0048] 1.4. Perform...

Abstract

Provided is a control system midpoint positioning method. A two-stage grid method is divided into two main stages: an off-line preprocessing stage and an on-line calculating stage. The off-line preprocessing stage brings in a multi-parametric quadratic programming theory, and a computer can automatically divide state space of a control system into a plurality of raised partitions and calculates to obtain the control rate corresponding to each partition. Then a hash table mesh region is formed on the state space, and each mesh region is performed by different processing. In the on-line calculating stage, the hash table mesh region where the present state point of the system is determined through a hash function, the state point partition is further searched, and the control rate corresponding to the partition is obtained, and system control output quantity is obtained through simple linear operation.

Description

technical field [0001] The present invention is aimed at the optimization of the midpoint positioning method of explicit model predictive control. The two-level grid method can not only greatly improve the online search efficiency of point positioning, but also make the off-line preprocessing process simpler and faster, and to a certain extent reduce the Data storage space requirements. Background technique [0002] In the traditional model predictive control, there are repeated online optimization calculations, which cause the controller to be overloaded and inefficient. In order to solve these problems, scholars such as Manfred Morari and Alberto Bemporad introduced the multi-parameter quadratic programming theory around 2002, and established an explicit model predictive control method system. It mainly uses the inherent piecewise affine law of the model predictive control system, according to the model, constraints, performance requirements and other information of the c...
