电液多变量位置系统的解耦控制

采用对角矩阵法对电液比例双阀控缸位置耦合控制系统进行解耦设计。并在实验装置中得到了实现。解耦控制中，针对结构耦合和外扰力作用，分别采用了反馈解耦和反馈全解耦方案，实验结果表明，该方法具有较好的解耦效果，且仅需采用两液压缸活塞的位移值就能实现，算法简单，易于工程应用。

Decoupling Control of Electro-hydraulic Multivariable Position Control System

Decoupling of the electro-hydraulic multivariable position coupling system is designed and experimented using diagonal matrix method. The feedback decoupling and feedback complete decoupling schenes are applied respectively to eliminate the effects of structure coupling and outside disturbance force on the decoupiling control. The results show that it has distinct decoupling effect. This method can be realized only by position value of two hydraulic cylinder piston,so that the algorithm is simple and easy to be applied in engineering.
