永磁同步电机可以作为直流无刷电机来控制，需要位置传感器来检测转子位置。本文研究了无位置和速度传感器的速度控制系统，通过自适应观测器估计电机的转子位置和速度。为了使状态方程线性化，引入了两个新的状态变量。因此，基于线性控制理论，设计了一种自适应观测器，使估计的速度和位置收敛到真实的速度和位置。证明了该系统是渐近稳定的。文中还讨论了系统的零速运行和观测器参数失配的影响。最后，实现了系统的速度控制。计算机仿真和实验表明，该系统是有效的。
A permanent magnet synchronous motor can be controlled as a DC brushless motor, for which the position sensor is needed for detecting the rotor position. In this paper, the research on speed control system without position and speed sensors is reported, where the rotor position and speed of the motor are estimated by means of an adaptive observer. To make the state equations linear, two new state variables are introduced. Consequently, based on the Iinear control theory, an adaptive observer is designed by which the estimated speed and position are converged to real ones. The system is verified to be asymptotically stable. The operation of the system at zero speed and the effects of the mismatched parameters used in the observer are also discussed. Finally, the speed control of the system is implemented. The computer simulation and the experiments show that the system is valid.
