中文摘要：

针对大型导弹电驱动垂直起竖过程中,伺服电机驱动起竖力大、负载时变、需对起竖速度进行实时跟踪等问题,采用反馈线性化控制策略,解决了交流永磁同步电机非线性系统中的角速度与电流相互耦合而不易控制的难题。分别选择以Id轴、Iq轴作为控制器的输入和以角速度ω、Id轴作为输入以及传统PI控制进行仿真实验,仿真结果表明：反馈线性化控制能提高起竖机构的动态响应速度,能有效防止起竖初始阶段电机速度出现反向的情况,提高其在起竖过程中负载的稳定性能,这对电驱动垂直起竖过程的控制具有一定的参考意义。

英文摘要：

During the erecting of the large missile driven electrically by motor, the servo motor has large erecting force and time-varying load, and the erecting speed should be tracked in real time. To solve the problems, feedback linearization control is adopted to solve the problem of angular velocity coupling with electric current in nonlinear systems of Permanent Magnetic Synchronous Motor （PMSM）. Simulation is made to traditional PI control and by taking Ij, Iq, and to, Id respectively as the inputs of the controller. The experiment result shows that： Control of PMSM based on feedback linearization can improve the dynamic response speed of erecting device, effectively prevent the possible reverse speed of motor in the initial stage of erecting, and increase the stability of the load during erecting. This is meaningful to the control of electric vertical erection for large missiles.
