摘要
目前,工业工程广泛应用非线性的PID控制、时滞特色、强耦合,控制效果不理想。虽然优化PID控制,自适应PID控制和非线性PID控制和PID控制的其他改良形式,但在根本的意义上说,PID的参数只能为满足生产过程控制目标的某一方面要求而整定的,使控制效果达不到最佳。对于许多复杂庞大的被控对象,有时难以建立有效的数学模型,模糊控制就应运而生。模糊控制就是利用模糊集合论,仿照人的模糊控制策略转化为计算机所能接受的控制算法,进而实施控制的一种理论和技术。
At present, industrial engineering, which is widely used in PID control of the Nonlinear, time-delay, Strong coupling, characteristics of the object to control the result is not satisfactory.Although Optimization PID control, adaptive PID control and nonlinear PID control and other improved forms of PID control. But in a fundamental sense, PID parameter only to meet production process control of a way for the whole set of requirements. This often can not achieve the best control effect, often can not meet the requirement and achieve the best control effect. For a large number of complex controlled object with its extemal environment. Sometimes an effective model difficult to establish. Fuzzy control is made. Fuzzy control is the use of fuzzy set theory, the reaction of people into the fuzzy control strategy for the control of a computer algorithm can accept, a further implementation of the control theory and technology.
