title = "Analysis and control strategy of open-loop starting characteristics of the hydrodynamic air bearing permanent magnet synchronous motor",
abstract = "This paper addresses the challenges of sensorless control and high-reliability open-loop starting for hydrodynamic air bearing permanent magnet synchronous motors used in spacecraft gyroscopes. A resistance torque feedforward-compensated I-F open-loop starting control strategy is proposed to enhance stability and efficiency. First, the friction characteristics during motor startup are systematically analysed, with mathematical models established for static friction torque and sliding friction torque. Focusing on stability challenges during the hydrodynamic air bearing motor starting process, an improved I-F control strategy is developed. This approach effectively suppresses speed fluctuations while reducing power consumption. Simulations demonstrate a 50\% reduction in starting current and minimized torque oscillations. Experimental validation confirms significant improvements in voltage stability and rotational speed smoothness during open-loop starting.",
