摘要
通过对制冷测试系统涡旋压缩机排气口压力的控制，介绍了获取被控对象数学模型的一种实用、简单的系统辨识方法．根据阶跃响应与脉冲响应之间的关系，通过实验得到阶跃响应数据和脉冲响应曲线．最终在频域范围内。
A method of simple and practical system identification is presented with the process of automatically adjusting the discharged pressure of the scroll compressor in refrigerant system. According to the relation of step response and pulse response, the step response data and pulse response curve are obtained, and then the mathematical model of controlled object by CAD language MATLAB in the frequency field is acquired.
