And the result is mainly arose from the simple structure of PID controller which decide the limitation of control quality when used to application, and it also results in bad performance when it is used to long time delayed system and un-stable object. For the same reason, PID controller just determines few zero and pole points which also lead to not so good control quality of the closed loop.
这主要是因为PID控制器结构上的简单性决定了它在控制品质上的局限性，并且这种简单性使得PID控制器对大时滞、不稳对象等被控对象的控制性能不是很好；同样，PID控制器只能确定闭环系统的少数零极点，无法得到更好的闭环控制品质；此外，PID控制器无法同时满足对设定值跟踪和抑制外扰的不同性能要求。
Traditionalnarrating methods and modem narrating methods are skillfully applied in narration, such as the reversion of omniscient perspective, the integration of diverse perspectives, the poetic zero-distance, the great-distance irony, the increase of timing-sequenceelement and narrating speed, the spacialization of linear time and the use ofjuxtaposition art. Plot structure is mainly used in structure, occasionally coupled withopen structure. For example, plot novel regards story as its basic element and restoresthe internal rules whereas open structure seems very simple in common with what weexpress. And life streams and serialized stories are more appropriate to original life. More direct speech and dialogic language have been embodied in discourse and somestories have changed their discourse form from monophonic solo to polyphonic choir, such as Bakhtin's polyphonic novel.
在叙述上，表现为传统叙述方法的普遍使用和现代叙述技巧的娴熟运用，如传统全知视角的复归、多样视角的综合、零距离的诗意化、大幅度距离的反讽性、顺时序成份的增加、叙述速度的加快、线性时间的空间化、并置艺术的应用，等等；在结构上，表现为情节型结构的主体地位和开放型结构的小比例使用，情节型结构让小说回到故事的基本面和构造故事的内在尺度，开放型结构则表现得很拙朴，和所要表达的内容紧密贴合，尤其是生活流形式和系列小说形式适合反映原生态的生活；在话语上，表现为直接引语的增加和对话性语言的涌现，一部分小说由传统的单声独唱转向多声合唱，形成如巴赫金所说的复调小说。
