The highly integrated valve-controlled cylinder (HIVC) is the joint driver in the hydraulic drive leggedrobot motion process, with the inner-loop-control-based outer loop dynamic compliance control method of the hydraulicsystem adopted. Yet the dynamic compliance of the HIVC position inner loop control has effects on theaccuracy of the outer loop dynamic compliance control. Therefore, the dynamic compliance parallel compositiontheory of the HIVC position inner loop control is presented and its dynamic compliance is analyzed in this paper,based on the HIVC position control nonlinear mathematical model. Moreover, the multiple parallel branch dynamiccompliance compound compensation control method is also designed and the dynamic compliance parallel compositionis rearranged. The experimental results indicate that adopting the compensation control method can decreasethe dynamic compliance of the HIVC position control system dramatically, which would provide the inner loopdynamic compliance compensation control method of the robot with high accuracy and high robustness.

Tower crane is of great importance in the construction of high rise buildings. A self-lifting & slewing multi-cranes platform (referred to as crane slewing platform) was developed to optimize the configuration of tower cranes, as well as solve the problems of cooperative operation conflict between multiple cranes and other construction equipment and their respective climbing and occupying of construction period. The design and test of the slewing platform was introduced. By applying the slewing platform in the construction of Chengdu Greenland Center super high rise building project, some key technologies such as the configuration of cranes, the installation, construction and lifting of the slewing platform are implemented and validated. Up to now, the slewing platform has been safely lifted up 98 times in Chengdu Greenland Center project construction, and achieved good social and economic benefits.
