This design uses 8088CPU the stepper motor control through 8255I / O port output with the timing of the square wave as a stepper motor control signal, the signal through the driver chip to drive a stepper motor。 本設(shè)計(jì)采用 8088CPU 對(duì)步進(jìn)電機(jī)進(jìn)行控制，通過 8255I/O 口輸出的具有時(shí)序的方波作 為步進(jìn)電機(jī)的控制信號(hào)，信號(hào)經(jīng)過驅(qū)動(dòng)芯片驅(qū)動(dòng)步進(jìn)電機(jī)； 實(shí)現(xiàn)步進(jìn)電機(jī)正反運(yùn)轉(zhuǎn)以及變速運(yùn)轉(zhuǎn)。 微電子學(xué)的迅速發(fā)展和微型計(jì)算機(jī)的普及與應(yīng)用，為步進(jìn)電動(dòng)機(jī)的應(yīng)用開辟了廣闊前景，使得以往用硬件電路構(gòu)成的龐大復(fù)雜的控制器得以用軟件實(shí)現(xiàn)，既降低了硬件成本又提高了控制的靈活性，可靠性及多功能性。這一線性關(guān)系的存在，加上步進(jìn)電機(jī)只有周 期性的誤差而無累積誤差等特點(diǎn)。成績 課 程 設(shè) 計(jì) 報(bào) 告 設(shè)計(jì)題目 步進(jìn)電機(jī)控制系統(tǒng)設(shè)計(jì) 課程名稱 計(jì)算機(jī)控制技術(shù) B 姓名 學(xué)號(hào) 班級(jí) 自動(dòng)化 0803 教師 設(shè)計(jì)日期 2020 年 7 月 8 日 計(jì)算機(jī)控制技術(shù)課程設(shè)計(jì)報(bào)告 I 步進(jìn)電機(jī)控制系統(tǒng)設(shè)計(jì) 摘 要 步進(jìn)電機(jī)是將電脈沖信號(hào)轉(zhuǎn)變?yōu)榻俏灰苹蚓€位移的開環(huán)控制元件。在非超載的情況下，電機(jī)的轉(zhuǎn)速、停止的位置只取決于脈沖信號(hào)的頻率和脈沖數(shù)，而不受負(fù)載變化的影響，即給電機(jī)加一個(gè)脈沖信號(hào)，電機(jī)則轉(zhuǎn)過一個(gè)步距角。使得在速度、位置等控制領(lǐng)域用步進(jìn)電機(jī)來控制變的非常的簡單。 在當(dāng)今社會(huì)的各個(gè)領(lǐng)域步進(jìn)電機(jī)無處不在， 應(yīng)用領(lǐng)域涉及機(jī)器人 、 工業(yè)電子自動(dòng)化設(shè)備 、 醫(yī)療器件 、 廣告器材 、 舞臺(tái)燈光設(shè)備 、 印刷設(shè)備 、 計(jì)算機(jī)外部應(yīng)用設(shè)備等等 。 關(guān)鍵詞：步進(jìn)電機(jī)；脈沖信號(hào)； 8088CPU； 步進(jìn)電機(jī)控制系統(tǒng)設(shè)計(jì) II Design for Stepper Motor Control System Abstract Stepper motor is the electric pulse signal into angular displacement or linear displacement of the openloop control ponents. In the case of nonoverloaded, the motor speed, stopping only depends on the location of pulse frequency and pulse number, regardless of load changes, that is, to add a pulse motor, the motor is turned a step angle. The existence of this linear relationship, with only periodic error of the stepper motor without the accumulation of errors and so on. Makes the speed, position and other control areas to control the stepper motor bees very simple. The rapid development of microelectronics and microputer popularization and application, the application for the stepper motor opens up broad prospects for making the past with large and plex hardware circuits of the controller can be implemented in software, not only reduces the hardware cost and improve the control flexibility, reliability and versatility. In today39。 to achieve positive and negative stepper motor and variable speed operation .
