First, the design requirements and design constraints are summarized by investigating the characteristics of HVSS structures. Then, the atlas of feasible structure is systematically generated by performing structural synthesis using graph theory. After that, the kinematic design method for the HVSS is proposed, then the input trajectory of the motors can be generated by the method. Moreover, the semi-closed-loop control architecture is adopted as the system model, and the design and analysis of controllers, including PID control, phase lead compensation, and genetic algorithms are conducted. Finally, two examples are given to illustrate the design process, a prototype machine is made, and an experimental setup is established to verify the feasibility and the effectiveness of the proposed design and analysis approaches. The experimental result show that the output of the proposed HVSS agrees well with the theoretical design. Therefore, the proposed system as well as its design and analysis approaches are feasible.
