自动控制原理实验教学中的计算机辅助测试

Computer Aided Testing in Experiment of Auto Control Theory

针对自动控制原理教学中经典实验的传统测试方法，提出一种用计算机作为辅助测试工具的测试方案．该方案利用软件数字示波器和数字频率特性测试软件完成对阶跃响应和频率特性的数字化测量，不仅提高了测试精度，而且由于采用了分布式测量思想，一机多用，大大节省了硬件测量设备费用．

In contrast to the traditional testing way using classical experiment in auto control theory teaching, a testing method using the computer as the auxiliary testingtool is introduced in this paper. By this method digital oscilloscope software and digitalfrequency characteristics software are used to complete the digital measurement of stepresponse and frequency characteristics. It not only improves the measuring precision,but also cuts down the cost of measuring equipment.
