| 摘要: | 一般在控制迴路中感測器為主要回授體，其開迴路設定會發散讓可靠度下降到沒法使用，而閉迴路設計因為有感測器作為回授體讓系統穩定，本文以比較開迴路與閉迴路為目標。
本文中以步進馬達求取最佳參數為實驗對象，使用Labview為軟體控制馬達的定位和轉速，並將系統裝設在一般電腦和工業電腦上做比較：一般電腦核心為Pentium D3.4G、工業電腦核心為Pentium Core 2T7400 2.16G，作業系統皆為Windows XP，藉以找出最佳的控制模式和參數設定，加上利用系統real-time 的特性，可以降低時間上的延遲，增加系統之可靠度及穩定性，藉以達到軟體和硬體同步化的目的，並選擇最節能及省時的方式，以求取系統的性能，足以滿足設計需求及符合最佳化，達到效能與成本的最完美平衡點，再透過有效的系統管理方式，達成既定之品質目標。
在未來利用微控制器來替代電腦，希望可以更加符合使用者需求，達到所需之品質管理，同時因為處理時間少，又可達成節能省時之目的，使工業化後，讓其可靠度提昇，且成本具有競爭性。
In the general control loop with main sensor feedback, in open loop without sensor will be divergence the data output let system reliability down and then cannot work. Closed-loop with the sensor feedback will stable the system finally.
This article is based on step motor to find optimization parameters for the subject. Using Labview software to real-time control the motor speed and position, and installs the system on the desktop computer and the industry computer does the comparison: The desktop computer core is Pentium D 3.4G, the industry computer core is Pentium Core 2 T7400 2.16G, the OS is Windows XP, then to find adaptive parameters to optimizing feedback system, and find the best control model and the parameter hypothesis, and using the system real-time characteristic, may reduce time delay, increases reliability and the stability in the system, to achieving hardware and software synchronize, and chooses conserves energy and the time-saving way, seeks system's performance, meets the design need and conforms to the optimization, achieves the balance point of potency and the cost, and using the effective system management, achieves decides the quality goal.
Will use the micro controller in the future, hoped that may will achieve needs the quality control, after causing the industrialization, will let its reliability promotion, and the cost will have competitiveness. |
