中文摘要 | 傳統閥控液壓伺服系統由釋壓閥及定排量泵組成,造成能源效率不佳。本文結合閥控液壓缸系統與節能控制系統,發展創新整合控制系統,同時結合節能控制與運動控制,實現高運動控制響應及高能源效率。全系統為二進二出控制系統,故本研究以迴路整形H(下標 ∞)控制減低兩系統間之耦合影響。而為同時兼顧時域與頻域規格,本文結合基因演算法選取最佳之迴路整形H(下標 ∞)控制器的權重函數。為比較節能控制之性能,運動控制分別於有節能控制及無節能控制實現,而運動控制分別實現軌跡追蹤控制及速度控制,最後以實際實驗於實驗系統上實際驗證及實現。 |
英文摘要 | Conventional electro-hydraulic servo control systems that incorporate positive displacement pumps and relief valves have a problem of low energy efficiency. The objective of this research is to implement parallel control of motion control and energy-saving control in an electro-hydraulic servo control systems to achieve both high motion control performance and high energy efficient simultaneously. The overall control system is a two-input two-output system. For that, the loop-shaping H(subscript ∞) control strategy is developed in this study to reduce the coupling interactions between the two subsystems. Moreover, in order to achieve both the frequency domain and time domain specifications at the same time, the genetic algorithm is used to select weighting functions of loop-shaping H(subscript ∞) control. To compare the energy-saving performance, the motion control is implemented with and without energy-saving control systems, respectively. The parallel control of motion control, including path control and velocity control, with energy-saving control in an electro-hydraulic servo system by the genetic algorithm based loop-shaping H(subscript ∞) control is implemented experimentally. |
