| 摘 要： | 考虑了一类永磁同步电动机的有限时间跟踪控制问题．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．有限时间跟踪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．

| Abstract: | For a class of permanent-magnet synchronous motor, the finite time tracking 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 so that system state reaches to the equilibrium point in a finite time. The bounded ness of all signals of closed loop system and the global stability of equilibrium point are guaranteed and the system states accurately track the states of the reference signal in a finite time. Finally, numerical simulation validates the efficiency of the control scheme. |
