This texts contemporary approach focuses on the concepts of linear control systems, rather than computational mechanics. Straightforward coverage includes an integrated treatment of both classical and modern control system methods. The text emphasizes design with discussions of problem formulation, design criteria, physical constraints, several design methods, and implementation of compensators.Discussions of topics not found in other texts--such as pole placement, model matching and robust tracking--add to the texts cutting-edge presentation. Students will appreciate the applications and discussions of practical aspects, including the leading problem in developing block diagrams, noise, disturbances, and plant perturbations. State feedback and state estimators are designed using state variable equations and transfer functions, offering a comparison of the two approaches. The incorporation of MATLAB throughout the text helps students to avoid time-consuming computation and concentrate on control system design and analysis

It mainly consists of two parts: MSP430 Launch Pad and main board. Compared with traditional microcontroller experiment equipment,a few analog circuits were added. The experiment we set up takes advantage of all microcontroller peripherals. Students can do two kinds of experiments: module experiment and complex experiment.Therefore it fits university students in automation and electrical major very well.

The GL823K integrates a high speed 8051 microprocessor and a high efficiency hardware engine for the best data transfer performance between USB and flash card interfaces. Its pin assignment design fits to card sockets to provide easier PCB layout. Inside the chip, it integrates 5V to 3.3V regulator, 3.3V to 1.8V regulator and power MOSFETs and it enables the function of on-chip clock source (OCCS) which means no external 12MHz XTAL is needed and that effectively reduces the total BOM cost.

單片機(jī)課程設(shè)計(jì) 籃球記分器 LANE STUDIO CONTENT 1 2 3 4 5 系統(tǒng)功能 課題運(yùn)用的知識(shí)點(diǎn) 系統(tǒng)原理的設(shè)計(jì) 硬件部分的設(shè)計(jì) 軟件部分設(shè)計(jì) 1 系統(tǒng)功能 PART 1 PART 1 隨著科技的迅猛發(fā)展,單片機(jī)在計(jì)算機(jī)應(yīng)用領(lǐng)域中起到了越來越重要的作用. 單片機(jī)體積小,功能強(qiáng),集成了微型機(jī)的各部件,大大縮短了系統(tǒng)內(nèi)信號(hào)傳送的距離,從而提高了系統(tǒng)的可靠性及運(yùn)行速度。 該系統(tǒng)主要是實(shí)現(xiàn)以下幾種功能: ① 計(jì)分:能同時(shí)顯示甲、乙兩隊(duì)比分,最大計(jì)分?jǐn)?shù)為99。能分別對(duì)甲、乙兩隊(duì)比分進(jìn)行加分。 ② 計(jì)時(shí):從比賽開始時(shí)啟動(dòng)計(jì)時(shí)工作方式,初始時(shí)間為00,最大計(jì)時(shí)為99 分鐘, 經(jīng)過修改后應(yīng)該還能實(shí)施計(jì)時(shí)暫停,還能設(shè)定為倒計(jì)時(shí)。 ③ 交換比分:中場(chǎng)交換比賽場(chǎng)地時(shí),能交換甲、乙兩隊(duì)比分的位置。 ④ 哨音提示:設(shè)定的比賽時(shí)間到了,能自動(dòng)哨音提示比賽結(jié)束. PART 1 2 課題運(yùn)用的知識(shí)點(diǎn) PART 1 PART 2 1 2 3 人機(jī)接口 AT89C51單片機(jī)的運(yùn)用 LED數(shù)碼管的運(yùn)用 本課題主要運(yùn)用單片機(jī)設(shè)計(jì)知識(shí)設(shè)計(jì)籃球賽記時(shí)計(jì)分器,因此涉及到的知識(shí)點(diǎn)主要有以下幾點(diǎn): 3 系統(tǒng)原理的設(shè)計(jì) PART 3 按 鈕 單片機(jī)芯 片 時(shí)間顯示 比分顯示 為了實(shí)現(xiàn)原理圖的設(shè)計(jì)目標(biāo),同時(shí)結(jié)合自己獲取的各種資料以及要達(dá)到的具體功能,所確定的組成框圖如圖。 一、組成框圖的組成說明 二、組成框圖的組成及其功能說明 1、LED能夠顯示比賽成績(jī)和比賽時(shí)間,并且能夠顯示調(diào)整后的比賽成績(jī)和時(shí)間 2、控制按鈕由兩隊(duì)的加分按鈕組成、以中場(chǎng)中止按鈕組成。 3、暫停比賽時(shí)間 4 硬件部分的設(shè)計(jì) PART 4 單片機(jī)接口電路 復(fù)位電路 1 復(fù)位是指單片機(jī)的CPU或系統(tǒng)中其它的部件處于某一確定的初試狀態(tài),并從這一狀態(tài)開始工作。除了進(jìn)入系統(tǒng)的正常初始化之外,當(dāng)由于程序運(yùn)行出錯(cuò)或是操作錯(cuò)誤使系統(tǒng)處于鎖死狀態(tài),為擺脫困境,需要進(jìn)行按鍵復(fù)位。 通常單片機(jī)的復(fù)位操作有上電復(fù)位、信號(hào)復(fù)位、運(yùn)行監(jiān)視復(fù)位,運(yùn)行監(jiān)視復(fù)位有程序運(yùn)行監(jiān)視和電源監(jiān)視。 在本設(shè)計(jì)中,則是采用上電復(fù)位,原理是當(dāng)電源接通后,上電瞬間RESET引腳獲取高電平,該高電平需要電容充電來維持,當(dāng)高電平維持在兩個(gè)機(jī)械周期以上則單片機(jī)能被復(fù)位。 PART 4 2 晶體振蕩電路 晶體振蕩電路用于產(chǎn)生單片機(jī)工作時(shí)所需的時(shí)鐘信號(hào),從而保證各部分工作的同步。單片機(jī)內(nèi)部有一個(gè)高增益反相反大器,只要在輸入端XTAL1與輸出XTAL2之間掛一個(gè)晶體振蕩器和微調(diào)電容就可以構(gòu)成一個(gè)穩(wěn)定的自激震蕩器并在單片機(jī)內(nèi)部產(chǎn)生的時(shí)鐘脈沖信號(hào)。電容器C1與C2用于穩(wěn)定頻率和快速起振,電容一般在5PF—30PF,本設(shè)計(jì)電容為30PF。 PART 4 3 鍵盤接口電路 與通用單片機(jī)相比,單片機(jī)應(yīng)用系統(tǒng)中的鍵盤種類很多,鍵盤中按鍵數(shù)量設(shè)置依系統(tǒng)操作要求而定。單片機(jī)應(yīng)用系統(tǒng)中的鍵盤有獨(dú)立式和行列式兩種。
