Problems solved by technology

[0004] However, the current application of the immune genetic algorithm in the PID controller generally uses a program on a platform such as MATLAB to iteratively optimize the PID parameters in an offline state, which cannot achieve effective online optimization and tuning.
Moreover, these algorithms are often applied to the distributed control system through the OPC interface, which has poor real-time performance and cannot realize visual online modification.
In addition, in industrial applications, since different PLC, IPC and DCS systems use different programming platforms, the versatility of these algorithms is greatly limited

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The basic principle of the immune genetic PID controller is to start from the initial random distribution group of PID parameters, select the PID parameter with the highest fitness in each sampling period as the PID controller parameter of the next sampling period, and calculate the fitness and antibody of the group at the same time. Concentration, and corresponding optimization processes such as selection, crossover, and mutation are performed on the population to produce a population that is better than the previous generation, which is copied to the next generation population, and the cycle continues.

[0033] The implementation method of the immune genetic PID controller based on the graphical configuration technology of the present invention is realized through the following technical scheme: the immune genetic PID control ...

Description

technical field [0001] The invention relates to the technical field of industrial automation control, in particular to a method for realizing an immune genetic PID controller based on graphic configuration technology. Background technique [0002] PID is one of the indispensable control links in the modern industrial production control process. The traditional PID has a simple structure and is easy to adjust, and has been widely used in various industrial production links. However, due to the rough parameter setting method of traditional PID, it is not conducive to the application in large-scale, time-varying and large-delay control objects, and has great limitations and disadvantages in complex process control. In addition, with the rapid development of today's distributed control system, the industrial production process also puts forward higher requirements for the real-time and online performance of the PID controller. Considering production safety and economic benefit,...
