Integrated Modeling Research On Structure And Control Of High-Speed And High-Accuracy Electromechanical System

Nowadays, the Mechatronical Systems need stricter requirement of dynamic precision and stability in the utmost condition. In traditional way, the mechanical structure of system is designed firstly, and the controller secondly. Therefore, the performance of whole system above can not be considered as the best one affirmatively, especially in utmost condition, as a result of being designed separately. Furthermore, no solution may be brought on. The reason of that is ignorance on the interaction and collision of the structure and control parameters. On account of this point, the Mechatronic design should be based on the unique model and all the parameters should be optimized simultaneously.A simultaneous design model of mechanical structure and control system is presented, in order to solve the Performance Bottleneck of the design of micro-electromechanical systems. By analyzing dynamic equation of virtual work, a dynamic model including structure and control parameters has been formed. Then, combining the theories of structural optimization and optimal control, the integrated design model is proposed.Configuring about the transducer of wire bonder, stability and response are set as object to optimize the system simultaneously. Feasible Region is changed and expended under this design model. comparing with the result of traditional method, the system performance has been improved efficiently This method can be applied to the design of micro-electromechanical systems with constraints of extreme motion environment.
