在MATLAB平台下开发了发动机试验台架的自动采集和控制系统。利用MATLAB中的数据采集工具箱开发了自动数据采集系统,可以实现实验数据的自动采集、处理、显示和储存等功能。另外,利用单片机开发了PID控制器系统,用来对发动机试验的进气温度和燃油温度等边界条件进行控制,成功地保证了发动机试验的一致性和可重复性。 In the MATLAB platform developed engine test bench automatic acquisition and control system. The data acquisition toolbox in MATLAB has been used to develop an automatic data acquisition system that can automatically acquire, process, display and store experimental data. In addition, a single-chip PID controller system was developed to control the boundary conditions such as intake air temperature and fuel temperature of the engine test, and successfully ensure the consistency and repeatability of the engine test.
