对模型跟踪自适应控制进行了新的探讨，提出了自适应滑模跟踪控制策略．对模型跟踪误差建立了滑动模型，实现了滑动模态控制，保证模型跟踪误差快速趋于零．该控制策略用于机械加工过程的仿真结果表明，其对机械加工过程参数变化的扰动有较好的适应性和较强的鲁棒性． A new approach to model tracking adaptive control is proposed. An adaptive sliding mode tracking control strategy is proposed. The sliding model is established for the model tracking error, and the sliding mode control is realized to ensure that the model tracking error tends to zero quickly. The simulation results of this control strategy used in machining process show that it has better adaptability and robustness to the disturbance of the variation of machining process parameters.
