摘要: 针对在煤层气开采过程中多个水力压裂水泵电动机的协调同步控制问题，提出了非线性滑模控制的方法，给出了水力压裂开采非线性滑模控制器的设计方法，并结合煤层气水力压裂系统对控制器性能进行了分析。仿真分析和实验结果表明，采用非线性滑模控制器后，在煤层气压裂开采中，煤层气的浓度和单孔流量均有较大程度提高。

Abstract: For coordination and synchronous control problem of multi motors of water pump for hydraulic fracturing in coalbed methane exploit process, a method of nonlinear sliding mode control was proposed, design method of nonlinear sliding mode controller for hydraulic fracturing of coalbed methane was given, and the controller performance was analyzed combining with hydraulic fracturing system of coalbed methane. The simulation analysis and experimental results show that concentration and single hole flow rate of coalbed methane were increased greatly in the process of coalbed methane fracturing exploit.
