【摘要】 本文应用状态空间理论,设计出了反馈矩阵,消除了电液伺服系统设计中的难题一负载特性,外干扰、交叉耦合作用的影响,提高了系统的动态性能。所设计出的反馈矩阵在工程上容易实现,以输出量作观察量时,不要外加检测元件,故具有较高的现实意义。更多还原

【Abstract】 This paper designs feedback matrix by means of state space theory to oliminate the influences of load character, external disturbance and cross-relevance, difficulty in designiny elector-hydraulic servo systems, this improving the dynamic qualiyt of the system. The feedback matrix is easy to realise, extra senser is not necessary if output serves as observa-biltiy. There fore, there is high practical importance.更多还原
