Besides , the electric power industry is a special industry , and some of its important sectors are in natural monopoly because of the characteristic of the network , which determines the government must supervise the electric power industry on price , entry , service and etc . because of the gradualness of the electric power reform and the limit of the inertia of original plan economy system , the new - type electric power supervisory system that meets the requirement of the market economy at present has not been set up yet in our country 电力产业又是一个特殊的行业,它的一些重要环节因网络特征明显而具有自然垄断性,这决定了政府必须对电力产业进行监管。尽管经历了20多年开放和引入竞争的电力体制改革实践,并于2003年3月成了国家电力监管委员会,但由于受电力体制改革的渐进性以及原有计划经济体制惯性的限制,监管改革进度缓慢,监管机构、监管职能、监管方式改进尚不明朗,我国目前符合市场经济要求的新型电力监管体系尚未真正建立。
The closed - loop transfer function matrix of such a system must be singular and an input controls two outputs in the system , so the closed - loop transfer function should be assumed a singular matrix whose elements are the fist - order inertia components , then the controller is designed . the control algorithm of closed - loop gain shaping is applied to the rudder roll damping system ( rrd ) 考虑到此系统的闭环传递函数阵一定是奇异的，以及具有一个输入控制两个输出的特点，在保证其中一个输出尽量小而另一个输出跟踪输入的前提下，将闭环传递函数阵即补灵敏度函数设为具有一阶惯性的奇异阵，设计出控制器。
Fuzzy control , as a main way of intelligent control , is widely used in every field of industrial production , but it is undisputable that fuzzy control has no high precision . the increasement of precision and elimination of vibration for fuzzy control is a new topic to develop fuzzy controller . thus , the researcher of fuzzy control has proposed various programs to solve the problems of this kind , which plays an important role in popularization of fuzzy control technology 模糊控制作为智能控制的最主要形式被广泛地应用于工业生产的各个领域，但是模糊控制精度不高却是不争的事实，提高模糊控制的精度、消除振荡成为模糊控制发展的新课题，为此，模糊控制的研究者提出了各种解决问题的办法，为模糊控制技术的进一步推广起到很重要的作用；对于大惯性的纯滞后系统实施的预测控制也是控制界的主要课题之一，传统的smith预估器需要对象的精确数学模型，而实际工程中的控制对象往往很难获得其精确数学模型，因此，控制精度高且具有预测功能的模糊控制器是解决这一大类问题首选控制方案。
