英文摘要： The low-carbon elevator adopting gearless traction mode is more suitable for the need of national energy saving and environmental protection planing, and it will be an indispensable transportation for modern high-rise buildings in the future. This project commits to the key scientic issues of the new-type permanent magnet traction system. In order to meet the demand for high-comfort and high-efficiency operation of the modern elevators, the weight- sensorless pre-torque control and the online efficiency optimization control method for the permanent magnet traction machine are researched. First of all, the complex nonlinear dynamic characteristics of the gearless traction system during the electromagnetic brake releases is revealed, and the complete electromechanical coupling model of the permanent magnet traction system can be established. According to the multiple control performance including starting comfort and fast response, the pre-torque control method based on multi-objective nonlinear programming searching theory without weight sensor installation is studied. Additionly, in order to resolve the traditional efficiency optimization control method overly dependent on the accurate motor loss model, an online efficiency optimization control of the traction machine based on model predictive control theory is
