摘　　要：目前大多数高校开设的“自动控制原理课程设计”是以Matlab为平台进行模拟仿真,比如根据给定幅值裕度等指标进行系统校正,纯理论的模拟仿真虽然效果快捷直观,却过于理想,与现实工程有较大出入,不利于培养学生实践动手能力。针对这个问题,本文对自动控制原理课程设计进行了改革与创新,设计了一套基于PID的水温控制系统,以STC90C516RD+单片机为主控芯片,键盘输入设定温度,并在LCD12864上显示设定温度和实时温度。经测试系统的静态控制误差≤0.3℃,十分钟左右能稳定在设定值,控制效果较好。本系统包含了单片机技术、传感器技术、自动控制原理等多学门学科技术,实践操作性强,是自动控制原理理论课程很好的实践环节。At present, most colleges and universities open “principle of automatic control course design” is based on the Matlab platform to carry on the simulation, such as according to the allowance for tentering value indicators system calibration, pure theoretical simulation effect fast and intuitive, but too ideal, engineering has great discrepancy with reality, is not conducive to cultivating stu-dents’ practice ability. Aiming at this problem, this paper has carried on the reform and innova-tion to the automatic control principle course design, designed a set of water temperature control system based on PID, STC90C516RD+ single-chip microcomputer as the main control chip, keyboard input setting temperature, and display the set temperature and real-time temperature on LCD12864. The static control error of the test system is less than or equal to 0.3˚C, and it can be stabilized at the set value in about ten minutes. The control effect is good. The system includes SCM technology, sensor technology, automatic control principle and other disciplines technology, practical operation is strong, is a good practice of the theory of automatic control course.
