介绍了无刷直流电动机(BLDCM)位置伺服系统离散时间变结构控制器的设计方法。数字仿真结果表明:变结构控制器具有健全的控制性能,对控制对象的参数变化及外部扰动并不敏感,系统状态将按预定的路径变化,因而伺服系统具有高稳定性、高精度、鲁棒性和快速响应等优点。 |

Abstract: |
In this paper the design of a discrete time variable structure controller(VSC) for a brushless DC motor drive (BLDCM) position servo system is introduced.Simulation results show that the VSC has perfect control performance and is insensitive to the parameter varation of controlled object and outside disturbance,and that the system state will change according to predetermined path,so the servo system has snch advantages as high stability,high accuracy?robustness and fast response. |
