四边滑阀控制液压缸传递函数的一种求解方法

A Derivation Method of Four-sltde Cylinder's Transfer Function

在关于液压控制系统的著作中 ,对四边滑阀对称液压缸 (或液压马达 )伺服系统 ,已有详尽分析和论述 ,但关于四边滑阀非对称液压缸伺服系统的论述却不多 ,且关于非对称阀控制非对称缸的传递函数的求解又有不同的论述[1 ]～ [4 ] ,本文试用一种方法求解四边滑阀控制液压缸的传递函数 ,对这一类问题加以补充。

In works and papers related to hydraulic control system, compared with detailed analysis and discussion in four-slide symmetric-cylinder servo system, little work had been concentrated on four-slide non-symmetric-cylinder servo system. And different solutions about transfer function of the system had been done [1]～[4] . In this paper,a new method is proposed to supplement this problem.
