摘要：

The inverse kinematics, singularity analysis, control strategies and experiments for the parallel manipulators with the thrust vector control (TVC) application are presented. Local control strategy (LCS) and global control strategy (GCS) are proposed and experimentally verified based on the architecture of the parallel manipulator. The fuzzy logic control (FLC) uses a form of quantification of imprecise information like input fuzzy sets to generate an inference scheme, which is based on a knowledge base of control signals to be applied to the system. The experimental results reveal that the LCS delivers lower positioning accuracy compared with the GCS.
