摘　　要：为了进一步提高滑模控制系统的控制性能,提出了混合非奇异终端滑模控制(hybrid nonsingular terminal sliding mode,HNTSM)策略,该控制策略结合线性滑模与非奇异终端滑模(nonsingular terminal sliding mode,NTSM)的优点,提高了系统状态的收敛速度,实现了状态变量的全局快速收敛,并设计控制函数,解决了终端滑模的奇异性问题。应用该方法设计永磁同步电动机(permanent magnet synchronous motor,PMSM)混合非奇异终端滑模速度控制器,并与PI调节器进行了仿真与实验对比。仿真和实验结果表明,该速度控制器能够有效地提高系统的静态、动态特性与鲁棒性。To improve dynamic quality of permanent magnet synchronous motor （PMSM） speed servo system, the hybrid nonsingular terminal sliding mode control method （HNTSM） was.proposed. The advantages of the linear sliding mode （LSM） and nonsingular terminal sliding mode （NTSM） were combined, the singular problem of the terminal sliding mode （TSM） was solved by this method. In addition, the faster convergence speed of system state variables could be obtained during the whole process. The novel control method was applied to the PMSM speed servo system, a novel sliding mode speed controller was designed to replace the traditional PI regulator. Simulation and experimental results show that the novel speed controller can improve steady, dynamic performances and robustness of speed servo system obviously.
