摘要
为了描述变形体的非线性变化规律，同时为了顾及外界环境因素对变形体的影响，本文建立了时不变和时变双线性混合回归变形模型与时不变和时变双线性动态系统变形模型。给出了双线性变形模型的动态参数估计。算例说明，对非线性变化趋势的变形体建立双线性变形模型的有效性和实用性。
In order to describe nonlinear regularities of a deformation body and consider simultane-ously the effects of various ambient factors on deformation，the bilinear mixed regression de- formation models and the bilinear dynamic systems deformation models are established re- spectively in two case of time-invarient and time－varying.The dynamic parameters estima- tion for these models are derived．The application examples demonstrate the effectivenessand practicality in which the bilinear deformation models for a deformation body with nonlin-ear varied trends was established.
