【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的辨识方法。该方法可以在装置正常工作的条件下，进行多次阶跃测试，获得阶跃模型更多还原

【Abstract】 The shortcoming of primary step measuring traditional oriented and the features of multivariate system,an identification method on multivariate system step response of multistep measuring based on Least Squares are given out.This method can obtain step model by proceeding multistep measuring on condition that device working normally.Application result indicated that it is feasible and practical on engineering.更多还原
