本文使用現代控制理論中的無靜差跟蹤控制系統理論與狀態觀測器理論,設計了俯仰、偏航兩個通道的氣動力控制系統和滾轉角穩定系統。The dissertation refers to comparatively full literatures in the field of vsc, and the development history and characteristics of vsc are summarized, and the elementary concepts, elementary definitions, elementary properties, elementary principles and design methods are particularly introduced, and the causes of the chattering phenomenon are systematically analysed, and the study status of the chattering phenomenon and the main methods to eliminate the chattering are elaborated. for the deficiencies of traditionary methods, three improved methods are developed, which are improved exponent reaching law solution, variable boundary layer solution and the solution by adding an auxiliary continuous control term. for uncertain linear systems, an adaptive fuzzy integral variable structure control stategy ( afivsc ) is put forward to eliminate the chattering around the sliding plane, which introduces fuzzy logic to soften the non - linear discontinuous sig nal in the control variable and utilizes adaptive theory to adjust output membership function according to how much the uncertainty of the system is
比較全面地查閱了關于變結構控制理論的文獻,總結了滑模變結構控制的發展歷史和特點,詳細介紹了變結構控制的基本概念、基本定義、基本性質、基本原理以及設計方法;系統分析了變結構控制系統抖振產生的機理,並闡述了國內外目前對抖振問題的研究現狀以及消除抖振的主要方法;針對傳統抑制和消除抖振方法的不足,改進了傳統方法,得到了三種新的消除抖振的方法? ?即改進的指數趨近律法、可變邊界層法和附加連續項法;針對不確定性線性系統,在變結構控制策略中引入模糊邏輯和自適應理論來消除滑動平面上的抖振,提出了一種自適應模糊積分變結構控制方案( afivsc ) ,利用模糊邏輯來柔化控制量中非線性不連續部分,採用自適應理論,根據系統不確定性大小在線調整模糊輸出量的隸屬函數,另外,鑒于模糊控制本質上是有靜差的,所以本文選擇了帶積分項的切換函數,由於積分項的存在使系統較正為無靜差系統。2u. s nuoxin 360 circling spray coating technology : the entire coating procedure is controlled by microcomputer to be of constant temperature an constant velocity. spry gun circles by 360 spraying powder ensuring complete atomization as well as evenness and stability of powder on plate surface after static absorption. and ultra - long process of high - temperature solidification in furnace resuls in still better performance of adhesion surface evenness and smoothness without blistering or color difference
2美國諾信360o旋轉噴塗技術:噴塗過程全程微電腦恆溫怛速控制,噴槍360o旋轉噴射粉末塗料,保證粉末塗料完全霧化,由板面靜電吸附后均勻穩定,通過超長程的固化爐高溫固化,附著力更強,表面更均勻更平滑,無起泡無色差。So the vsr can operate in any power factor. internal model control ( imc ) design concept has been introduced to the unbalanced control system of vsr. with imc design concept, the unbalanced control system not only achieve zero steady state error of sinusoidal ac current, but also obtains strong robustness of the control system
由於在abc和靜止坐標系中,採用比例和比例積分調節器無法實現對時變正弦波信號的無差跟蹤控制,而在dq坐標系中需要用正、反兩套旋轉坐標系構成四個電流內環才能實現對正、負序dq電流的無差跟蹤。Too early switch can not present the advantage of fuzzy controller and even lead to integral saturation, while too late switch can not turn into pid control because of the static state error of fuzzy - ped control. at last, the choice principle of the threshold is analyzed and simulated
當過早地切換會體現不出模糊控制的優點而使超調量增大,甚至造成積分飽和現象使系統失穩;當過遲切換,如果模糊控制器有較大的靜差,則有可能根本無法進入pid控制。The prominent character of the approach is that the flc can on - line search for the steady - state control value needed for the zero - error tracking, and optimize the fuzzy control table dynamically
該方法的顯著特點是,能夠在線搜索無靜差跟蹤所需要的穩態控制量,同時動態優化模糊控制量表。It not only can resolve the problem that it is difficult to establish the mathematic model of the dissolved oxygen concentration, but also can overcome the drawback that the general planar controller ca n ' t eliminate the static receiver error, but only has good dynamic characteristic
它不僅解決了污水處理中溶解氧濃度數學模型難確立的問題,而且能夠克服一般的二維模糊控制器僅有較好的動態特性,而無法消除靜態誤差的缺陷。分享友人
