文中考虑了一类永磁同步电动机的终端滑模控制器设计问题.在控制器设计中利用中继切换控制使系统在给定的当前控制律的作用下运行到某一特定状态（或某一特定区域）后,控制律被切换到有限时间收敛的终端滑模控制器,使得系统在有限时间内达到平衡状态.终端滑模控制器的设计保证了闭环系统所有信号的有界性和平衡点的全局稳定性,以及系统在有限时间内精确地跟踪给定的参考信号.最后,通过一个数值仿真验证了所提算法的正确有效性.
文中攷慮瞭一類永磁同步電動機的終耑滑模控製器設計問題.在控製器設計中利用中繼切換控製使繫統在給定的噹前控製律的作用下運行到某一特定狀態（或某一特定區域）後,控製律被切換到有限時間收斂的終耑滑模控製器,使得繫統在有限時間內達到平衡狀態.終耑滑模控製器的設計保證瞭閉環繫統所有信號的有界性和平衡點的全跼穩定性,以及繫統在有限時間內精確地跟蹤給定的參攷信號.最後,通過一箇數值倣真驗證瞭所提算法的正確有效性.

For a class of permanent-magnet synchronous motor,the terminal sliding mode controller design problem is considered.During the control process,the first phase is to induce the system state into a prescribed state（or region） under the current control law by using the relay switching control,the second phase is to switch to a terminal sliding mode control such that system state reaches to the equilibrium point in a finite time.The boundedness of all signals of closed loop system and the global stability of equilibrium point are guaranteed and the system accurately tracks the given reference signal in a finite time.Finally,the numerical simulation validates the effictiveness of the control scheme.
