Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] The present invention is an automatic controller design method based on the idea of ​​"library" and intelligent optimization algorithm, such as figure 1 As shown, the specific steps are as follows:

[0043] Step 1. Build link library

[0044]Some typical control links or other self-defined control links (clear physical meaning, simple and achievable) that may be required by the controller structure are built into a library as the basic elements of the controller. The mathematical model of each control link uses the transfer function Form representation. Each link in the link library is not an exact mathematical model, but a pending model with unknown control parameters, in order to realize the optimal design of the controller. Each control link has at least one control parameter to be optimized, and the number of parameters to be optimized i...
