    摘要:

    分析節能控制系統誤差會(huì )受到地域和空間環(huán)境限制,導致傳統方法分析結果精準度較低,針對該問(wèn)題,提出了時(shí)域方法對欠驅動(dòng)多軸機械節能控制系統誤差進(jìn)行分析。從系統控制時(shí)域響應角度出發(fā),研究控制系統在靜態(tài)響應和動(dòng)態(tài)響應兩方面的控制誤差。通過(guò)靜態(tài)響應特點(diǎn)構流程圖,并計算靜態(tài)誤差,以計算結果為依據分析輸入信號對靜態(tài)誤差影響,可改善空間限制問(wèn)題;通過(guò)動(dòng)態(tài)響應特點(diǎn)繪制過(guò)程曲線(xiàn),并計算動(dòng)態(tài)誤差,以計算結果為依據研究不同時(shí)間段對動(dòng)態(tài)誤差影響,可改善地域限制問(wèn)題。由實(shí)例對比結果可知,時(shí)域方法對系統控制誤差分析結果精準度較高,最高可達到90%,為工業(yè)控制系統提供時(shí)域方面信息。

    Abstract:

    The analysis of the error of the energy saving control system will be restricted by the regional and spatial environment, which leads to the low precision of the traditional method analysis results. In view of the problem, the time domain method is proposed to analyze the error of the under actuated multi axis mechanical energy saving control system. From the point of view of system control time domain response, the control error of control system in two aspects of static response and dynamic response is studied. Through the static response characteristics, the flow chart is constructed and the static error is calculated. Based on the calculation results, the influence of the input signal on the static error can be analyzed. The space limitation can be improved, the process curve is drawn and the dynamic error is calculated by the dynamic response characteristics, and the dynamic error is influenced by the calculation results on the basis of studying the dynamic error on the basis of the calculation results. The problem of regional restrictions can be improved. The result of the case comparison shows that the time domain method has a high precision for the system control error analysis result, and the maximum can reach 90%. The time domain information is provided for the industrial control system.
