Figure 114 Output from an interpolative firstorder hold (polygonal hold) 52 ? Digital Controllers and Analog Controller ? Analog Controllers ? represent the variables in an equation by continuous physical quantities. ? can easily be designed to serve satisfactory as nondecisionmaking controllers ? the cost increases rapidly as the plexity of the putations increases 15 Concluding Comments 53 ? Digital Controllers ? operate only on numbers ? decision making is one of their important functions ? handle nonlinear control equations involving plicated putations or logic operations ? use very much wider class of control laws ? flexible in allowing programming changes ? superior in performance and lower in price than their analog counterparts ? highly reliable, and often pact and lightweight ? less sensitive to noise signals 15 Concluding Comments 54 ? Outline of the Book ? The objective of the book: Understand, analyze and design CCS ? Chapter 1: introductory materials ? Chapter 2: z transform theory ? z transforms of elementary functions, important properties and theorems of the z transform, the inverse z transform, and the solution of difference equations by the z transform method ? Chapter 3: z plane analysis of discretetime control systems ? Impulse sampling and reconstruction of original signals from sampled signals, pulse transfer functions, and realization of digital controllers and digital filters 15 Concluding Comments 55 ? Chapter 4: Design of discretetime control systems by conventional methods ? mapping between the s plane and the z plane, stability analysis, transient and steadystate response analysis, design by the rootlocus and frequency response methods, and an analytical design method ? Chapter 5: statespace analysis ? Statespace representation, the solution of discretetime state space equations, and the pulse transfer function matrix, discretization of continuoustime statespace equations and Lyapunov stability analysis ? Chapter 6: Pole placement and observer design ? controllability and observability, design techniques based on pole placement, fu11order state observers and minimumorder state observers, the design of servo system 15 Concluding Comments 56 靜夜四無鄰,荒居舊業(yè)貧。 , February 6, 2023 雨中黃葉樹,燈下白頭人。 15:25:2915:25:2915:252/6/2023 3:25:29 PM 1以我獨(dú)沈久,愧君相見頻。 :25:2915:25Feb236Feb23 1故人江海別,幾度隔山川。 15:25:2915:25:2915:25Monday, February 6, 2023 1乍見翻疑夢,相悲各問年。 :25:2915:25:29February 6, 2023 1他鄉(xiāng)生白發(fā),舊國見青山。 2023年 2月 6日星期一 下午 3時(shí) 25分 29秒 15:25: 1比不了得就不比,得不到的就不要。 2023年 2月 下午 3時(shí) 25分 :25February 6, 2023 1行動(dòng)出成果,工作出財(cái)富。 2023年 2月 6日星期一 3時(shí) 25分 29秒 15:25:296 February 2023 1做前,能夠環(huán)視四周;做時(shí),你只能或者最好沿著以腳為起點(diǎn)的射線向前。 下午 3時(shí) 25分 29秒 下午 3時(shí) 25分 15:25: 沒有失敗,只有暫時(shí)停止成功!。 , February 6, 2023 很多事情努力了未必有結(jié)果,但是不努力卻什么改變也沒有。 15:25:2915:25:2915:252/6/2023 3:25:29 PM 1成功就是日復(fù)一日那一點(diǎn)點(diǎn)小小努力的積累。 :25:2915:25Feb236Feb23 1世間成事,不求其絕對圓滿,留一份不足,可得無限完美。 15:25:2915:25:2915:25Monday, February 6, 2023 1不知香積寺,數(shù)里入云峰。 :25:2915:25:29February 6, 2023 1意志堅(jiān)強(qiáng)的人能把世界放在手中像泥塊一樣任意揉捏。 2023年 2月 6日星期一 下午 3時(shí) 25分 29秒 15:25: 1楚塞三湘接,荊門九派通。 2023年 2月 下午 3時(shí) 25分 :25February 6, 2023 1少年十五二十時(shí),步行奪得胡馬騎。 2023年 2月 6日星期一 3時(shí) 25分 29秒 15:25:296 February 2023 1空山新雨后,天氣晚來秋。 下午 3時(shí) 25分 29秒 下午 3時(shí) 25分 15:25: 楊柳散和風(fēng),青山澹吾慮。 , February 6, 2023 閱讀一切好書如同和過去最杰出的人談話。 15:25:2915:25:2915:252/6/2023 3:25:29 PM 1越是沒有本領(lǐng)的就越加自命不凡。 :25:2915:25Feb236Feb23 1越是無能的人,越喜歡挑剔別人的錯(cuò)兒。 15:25:2915:25:2915:25Monday, February 6, 2023 1知人者智,自知者明。勝人者有力,自勝者強(qiáng)。 :25:2915:25:29February 6, 2023 1意志堅(jiān)強(qiáng)的人能把世界放在手中像泥塊一樣任意揉捏。 2023年 2月 6日星期一 下午 3時(shí) 25分 29秒 15:25: 1最具挑戰(zhàn)性的挑戰(zhàn)莫過于提升自我。 2023年 2月 下午 3時(shí) 25分 :25February 6, 2023 1業(yè)余生活要有意義,不要越軌。 2023年 2月 6日星期一 3時(shí) 25分 29秒 15:25:296 February 2023 1一個(gè)人即使已登上頂峰,也仍要自強(qiáng)不息。 下午 3時(shí) 25分 29秒 下午 3時(shí) 25分 15:25: MOMODA POWERPOINT Lorem ipsum dolor sit, eleifend nulla ac, fringilla purus.
