关于单片机方面的英文文献，最还有翻译

Answer 1

本毕业设计课题是属于教师拟定性课题，主要是研究基于单片机的对步进电机的有效控制。步进电机是一种能将数字输入脉冲转换成旋转或直线增量运动的电磁执行元件，每输入一个脉冲电机转轴步进一个步距角增量。电机总的回转角与输入脉冲数成正比例，相应的转速取决于输入脉冲频率。
步进电机是机电一体化产品中关键部件之一，通常被用作定位控制和定速控制。步进电机惯量低、定位精度高、无累积误差、控制简单等特点。广泛应用于机电一体化产品中，如：数控机床、包装机械、计算机外围设备、复印机、传真机等。

Abstract
This article mainly elaborated has been hanging the movement control system merit, introduced was hanging the movement control system function, the principle and the design process. Is hanging the movement control system is one of in control engineering domain important applications, its main target is to is controlled the object the movement condition, including path, speed and position implementation check. The movement control system compares with other control systems, has the system model simply, the check algorithm is unitary, also not complex characteristic and so on non-linearity and coupling situation. Also is precisely because the movement control system can implement to the path, the running rate, the pointing accuracy as well as the repetition precision accuracy control requirement, has the broad application foreground in each category of control engineering, therefore the movement control system has at present become in the check study application domain very much significant the research direction. Through the monolithic integrated circuit to stepping monitor check, implemented the motor-driven to cause the object at on the board which inclined the movement, The control section is the SST89E52 monolithic microcomputer which SST Corporation produces primarily, with when the 1602LCD liquid crystal screen and according to turned has implemented with the user interactive, through the keyboard entry different control command, the liquid-crystal display was allowed to display the setting value and the run the coordinates. The electrical machinery control section used LM324N four to transport puts and is connected the electronic primary device voluntarily to develop the 42BYG205 stepping monitor actuation electric circuit to implement the electrical machinery accuracy control. The algorithm partially for will suit the monolithic integrated circuit system to operate carries on optimizes many times, will reduce the microprocessor the operand. Has completed the object voluntarily the movement and according to the different setup path movement.
Key words Magneto; 1602LCD; LM324N; Drive circuit
