摘　　要：针对传统的一次阶跃测试的缺点和多变量系统的特点 ,提出了一种基于最小二乘的多次阶跃测试的多变量系统阶跃响应模型辨识方法 .该方法可以在装置正常工作的条件下 ,进行多次阶跃测试 ,因而在工程上是比较实用的 .A least square based multi step test method for model identification of multivariable step response is presented. It overcomes the disadvantages of the traditional one-step test, and especially applicable to multivariable system. The notable characteristic of this method is that the multi step test can be done under the normal operation, and that it has strong practicality on the real engineering. Simulation demonstrates its feasibility.
