在下的毕业设计, 本题要求设计一个直流电机控制系统。在设计中,采用国产单片机中目前比较新式的STC12C5A60S2作为整个控制系统的控制电路的核心,因为STC12C5A60S2内部有PCA模块,可以产生PWM波形;采用带中断的独立式键盘作为命令的输入,每当按键时蜂鸣器响;配以LCD12864显示实现对带光码盘的直流电动机转速参数的测量、显示和控制。LMD18200驱动模块内部是H型驱动电路,驱动能力较强,完成电机正反转以及速度的控制。为优化直流电机的响应,采用PID反馈,实现闭环控制。(Graduation in the next, and that the requirements to design a DC motor control system. In the design, the use of the relatively new domestic microcontroller as a control circuit of STC12C5A60S2 entire control system core, because STC12C5A60S2 internal PCA module can generate PWM waveforms using a separate keyboard with interrupt input as a command, whenever the button When the buzzer sounds accompanied LCD12864 display realize the measurement of the optical encoder with DC motor speed parameters, display and control. LMD18200 internal drive module is H-drive circuit, driving ability, and the speed of completion of the motor reversing control. In order to optimize the response of DC motor, using PID feedback, closed loop control.)

Vacuum-pumping-speed-graph
真空机组先启动SK-30水环真空泵带压力降到6.5 KPa(此时真空机组的抽速是SK-30的抽速)启动ZJP-1200(此时真空机组的抽速是ZJP-1200抽速)待压力降到4 KPa启动ZJP2500(此时真空机组的抽速是ZJP-2500抽速)待压力降到1kpa时最后启动ZJP5000(此时真空机组的抽速是ZJP-5000抽速)到100Pa达到使用真空度时时就可以关闭机组(Vacuum unit first start SK-30 water ring vacuum pump with pressure drops below 6.5 KPa (pumping speed of the vacuum unit at this time is SK-30 pumping speed) start ZJP-1200 (pumping speed of the vacuum unit at this time is ZJP-1200 pumping speed ) until pressure drops below 4 KPa start ZJP2500 (pumping speed of the vacuum unit at this time is ZJP-2500 pumping speed) until the last start when pressure drops 1kpa ZJP5000 (pumping speed of the vacuum unit at this time is ZJP-5000 pumping speed) to 100Pa achieved using vacuum unit can be closed from time to time)

SOES-master
Simple Open Source EtherCAT Slave
====
SOES (Simple OpenSource EtherCAT Slave Stack) is an opensource slave
stack that is very easy to use and provides a small footprint. It is a
good alternative to more complex stacks on the market.
Overview
SOES is an EtherCAT slave stack written in c. Its purpose is to learn and
to use. All users are invited to study the source to get an understanding
how an EtherCAT slave functions.
Features as of 1.0.0:
- Address offset based HAL for easy ESC read/write access via any
interface
- Mailbox with data link layer
- CoE
- Object dictionary
- SDO read and write for all sizes including segmented transfers
- Easy portable C-code suited for embedded applications
- Fixed PDO mapping
- FoE with bootstrap template
- Support for Little and Big endian targets.
- Polling for interrupts
