Description
Technical Field
The invention relates to the field of intelligent control, in particular to a washing machine door safety control system.
Background
The idea of intelligent control has emerged in the 60's of the 20 th century. At that time, studies on learning control were actively conducted and achieved good application. For example, self-learning and self-adaptive methods are developed for solving the random characteristic problem and model unknown problem of the control system; professor fujie jingsun (k.s.fu) at the university of universal ferris in 1965 first applied heuristic inference rules of AI to the learning control system; mendel (j.m. mendel) in 1966 first claimed the use of AI for the design of airship control systems.
In 1967, leion des (c.t. leondes), et al, in the united states, formally used the word "intelligent control" for the first time. In 1971, fujingsen discussed the cross-relationship between AI and automatic control. From now on, automatic control and AI begin to collide and knock out the spark, a new and emerging cross domain-intelligent control is established and developed. Early intelligent control systems employed relatively rudimentary intelligent methods, such as pattern recognition and learning methods, and developed at a very slow rate.
Zad published the famous paper "Fuzzy Sets" in 1965, opening up a new field of mathematics based on Fuzzy logic representing the ubiquitous uncertainty of human perception and language expression, Fuzzy mathematics. In 1975, maddani, england, successfully applied fuzzy logic and fuzzy relationships to industrial control systems, and proposed a fuzzy control method that could handle fuzzy uncertainty, mimicking human operating experience rules. After that, in two aspects of the theory and the application of the fuzzy control, a large amount of research is carried out by control experts, and a lot of interesting achievements are obtained, so that the intelligent control method is regarded as an intelligent control method which is very active and deep in development in the intelligent control.
In the 80's of the 20 th century, a rule representation and inference technology based on AI (especially an expert system) rule-based expert control system was rapidly developed, such as an expert control in austronm (k.j.astrom) in sweden, an expert control in robot control in saridis (g.m.saridis) in usa, and the like. With the re-rise of artificial neural network research in the middle of the 80 s of the 20 th century, researchers in the control field propose and rapidly develop a neural network control method which fully utilizes good nonlinear approximation characteristics, self-learning characteristics and fault-tolerant characteristics of the artificial neural network.
With the development and the deepening of research, conditions for forming intelligent control new disciplines are gradually mature. In 8.1985, the first academic conference on intelligent control was held by IEEE in new york, united states, discussing the principles and system architecture of intelligent control. Thus, intelligent control is widely recognized and rapidly developed as an emerging discipline.
In recent decades, with the development of intelligent control methods and technologies, intelligent control has rapidly moved to various professional fields, and is applied to control problems of various complex controlled objects, such as industrial process control systems, robot systems, modern production manufacturing systems, traffic control systems, and the like.
