摘要：本研究旨在發展液壓射出成型機之智慧型節能控制，針對液壓射出成型機之製程，特別是射出缸之製程，進行分析研究，在不影響原系統之響應性能前題下，發展合適之節能控制策略，提升液壓射出成型機之能源效率，液壓射出成型機之射出製程，主要以射出缸進行速度控制及力量(或壓力)控制，本研究將發展智慧型之節能控制器及控制策略，節能控制策略將分別發發展負載感測控制(Load-sensing control)、定供油壓力控制(constant supply pressure control)以及定功率控制(constant supply power control)，節能控制系統將以高響應電動馬達搭配液壓泵，以變轉速液壓泵方式實現節能控制。同時將設計及建立節能控制系統整合射出成型機射出缸伺服控制實驗系統，以實驗方式驗證整合節能控制後之射出缸伺服性能及耗能之改善。
Abstract: High servo control response and high energy efficiency, which are difficult to be achieved simultaneously, are requested in hydraulic servo systems of current hydraulic injection moulding machines. This investigation develops new solutions to concurrently implement energy-saving control and velocity-force control for simultaneously realizing high velocity-force control response and high energy efficiency for injection moulding machines. Two different hydraulic pump systems, including variable displacement pump and variable rotational speed pump, are developed and in each one of them two different energy-saving control concepts, such as load-sensing control and constant supply pressure control, are implemented. Thus, for verifying the feasibility of the integrated control systems and comparing the energy-saving effects, velocity-force control of the hydraulic cylinder can be integrated with four different energy-saving control systems and also the conventional hydraulic system without energy-saving control. The experimental results show the excellent performance of the integrated concurrent control systems.
