本文利用方块图的变换法则,将阀控液压缸的多反馈回路的方块图,转变成为具有单一反馈回路的方块图.然后,再由传递函数和迭加原理求出阀控液压缸的动态方程.
In this paper, the block diagram is used to transform the block diagram of the multi-feedback circuit of the valve-controlled hydraulic cylinder into a block diagram with a single feedback loop. Then, the dynamic equation of the valve-controlled hydraulic cylinder is derived from the transfer function and the superposition principle. .
