Based on the analysis of the mechanism of robot manipulators, a trajectory tracking controlling research model is first built up with ADAMS, and its mathematical model is formulated through the study of robot kinematics and dynamics. After the modeling errors are analyzed in practical robotic systems, a conception of centralized error is brought forward according to the theory of weighting functions. In the case of modeling errors' exist, the robotic uncertain model is derived by introducing an auxiliary control variable into inverse dynamic analysis. The control strategy of robust exponential convergence is applied to the robotic uncertain model, the applicable conditions and the applicable controller with this application are presented. The stable control effect under three main model uncertainties (parametric errors, joint disturbs, joint frictions) are systematically studied on the previously built research model. The problems of robust exponential convergence controller which often results in unstable output and so produces a large relative error when the input trajectory is in a small range are resolved by adjusting the control parameters based on the controller's structure.

In control, however,the weak expression ofCY3 mRNA can be found after 48 hours of chilling and showed little increase at the third day instress.

非逆境条件下，IPT对秧苗根系中mRNA的表达差异与对照相比没有很大的变化；低温胁迫3天后，IPT对根系中mRNA的表达影响很大，既能增强某些基因的表达，又能抑制另一些基因的表达；用DDRT-PCR技术，寻找到5个低温胁迫下在对照和IPT处理中差异表达的基因，其中CY3片段与水稻CDPK1和CDPK2的mRNA有很高的同源性，初步断定CY3在植株的抗逆反应中可能具有与CDPKs相似的功能；在Genbank中没有检索到与其它4个片段同源性比较高的已知序列；IPT处理中CY3表达量在低温处理24hr就有明显升高，以后随胁迫时间的延长其表达量不断加强；恢复常温后，CY3表达继续增加，在恢复第14天开始下降，下降速度缓慢，IPT对CY3的影响一直延续到苗末期，对照中CY3在低温胁迫48hr才有微弱表达，72hr后表达量并未增加许多；恢复常温后第4天就开始下降，很快降到最低。
