| 摘 要： | 研究单框架控制力矩陀螺系统的外框架结构.系统的永磁同步伺服电机采用正弦波驱动;电流环采用电压空间矢量脉宽调制方法驱动逆变器;位置环采用模糊自适应滑模变结构控制,通过引入切换控制增益的模糊自适应调节方法来提高系统的鲁棒性和抗扰能力.在Matlab下对系统进行仿真,结果表明,采用模糊自适应变结构控制方法设计的伺服系统有较高的动态和稳态精度;抗扰性能得到加强;消除了滑模变结构控制器的抖振现象.

| Abstract: | Single gimbal control moment gyro(SGCMG) servo system is studied.Permanent magnet synchronous motor(PMSM) in the system is driven with sine wave;vector control strategy is used to control the inverter in the internal current loop;the external position loop is designed with fuzzy adaptive sliding mode control(FASMC) that fuzzy adaptive method is applied to regulate the gain of switch control variable.The simulation demonstrates that the system with FASMC controller has a high dynamic and steady precision,and is also robust.At the same time,the quiver brought by conventional sliding mode control is greatly weakened. |
