阐明如何通过人工智能技术(如知识库产生式系统等)与有效应用 PID 控制器的某些新颖想法相结合来构成一种性能更理想的创新的 PID 控制系统。文中所创新的系统直接辨识与系统瞬态和稳态性能紧密相关的控制特性;借助于人工智能技术,以一种由对所获得信息进行判断来决定采用每一种控制模式(如 P、I 及 D 模式,两种甚至三种作用的联合模式,以及开环和闭环控制相结合作用的模式等)的新型方法,使系统能按更良好的方式运行.这种创新的 PID 控制系统在对象或系统带有明显不确定性、非线性以及其它所不希望的控制特性时,拥有更多的智能作用,并且系统应该是更快速、更精确和更稳定的.通过比较获得的仿真结果证明,本文所创新的系统在自动控制实践中是一种具有广泛应用价值的技术方法.
It shows how to combine the new ideas of effective application of PID controller with artificial intelligence technology (such as knowledge base production system) to form an innovative PID control system with better performance. The innovative system in this paper directly identifies the control characteristics which are closely related to the transient and steady state performance of the system. By means of artificial intelligence technology, a decision is made to determine whether to adopt each control mode (such as P, I And D mode, a combination of two or even three modes, as well as a combination of open-loop and closed-loop control, etc. The innovative method of PID control allows the system to operate in a more optimal manner Or the system has obvious uncertainties, non-linearities and other undesirable control features, it has more intelligence and the system should be faster, more accurate and more stable. The simulation results obtained by comparison show that, The innovative system in this paper is a kind of technical method with extensive application value in the practice of automatic control.
