摘 要: 为了提高电液伺服系统的控制效果,本文将模型参考自适应控制和滑模控制相结合,用模型参考方法来保证系统的稳态品质,用滑模控制方法来改善系统的动态品质,提出一种新的模型参考滑模自适应控制方法,仿真结果表明,该方法能有效抑制参数扰动、量测噪声及干扰,具有很强的鲁棒性。 In order to improve control efficiency for electrohydraulic servo system, combining model reference adaptive control theory with sliding mode control theory, a new model reference sliding mode adaptive control method was proposed for electrohydraulic servo system with the model reference control to guarantee steady - state quality of the control system and the sliding mode control to improve dynamic - state quality of the control system. The simulation results show that the controller can suppress parameter variation, external disturbances and measured noise effectively, it has strong robustness.
