摘　　要：利用输入输出反馈线性化方法、反演设计法与滑模变结构控制相结合的控制策略。结合自适应估计模型参数和扰动的不确定性,综合考虑控制律和不确定性自适应估计律,达到采煤机自动调高液压系统期望的性能指标。仿真试验结果表明,该控制策略能够实现高精度、快速稳定位置跟踪,对外扰动和模型不确定性具有较强的鲁棒性。该方法可以为采煤机自动调高液压系统控制提供有效参考。A control strategy combining input-output feedback linearization method,inverse design method,and sliding mode variable structure control.By combining the parameters of the adaptive estimation model with the uncertainty of disturbances,and taking into account both the control law and the uncertainty adaptive estimation law,the expected performance indicators of the hydraulic system for automatic height adjustment of the coal mining machine can be achieved.The simulation test results show that the control strategy can achieve high-precision,fast and stable position tracking,and has strong robustness to external disturbances and model uncertainties.This method can provide effective reference for the hydraulic system control of automatic height adjustment of coal mining machines.
