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.

This thesis inductively points out where the logicians did not satisfied with the theory of type mainly lies in two points, the axiom of reducibility first and the vicious-circle principle second. This thesis has discussed Ramsay's improvements as well as the criticism from Godel. Then, it observes that they two had a common view, viz. rejecting the vicious-circle principle from the points of Realism. Against Russell's insisting on this principle, such a rejecting seems so distinguished, which, this thesis argued, was the deep difference between Realism and Nominalism shedding on the reality of classes.
