The invention provides a control method for stable hovering of a high-voltage permanent-magnet direct-drive elevator, and belongs to the technical field of mining elevators, and the control method comprises the following steps: compensating a braking angle of a permanent-magnet synchronous motor by using a first PI controller to obtain a hovering angle compensation amount; the hovering braking torque is calculated according to the hovering angle compensation amount, the hovering angle compensation amount is adjusted until the hovering braking torque is matched with the load torque, and the adjusted hovering braking angle is output; according to the invention, hovering control is carried out through a current closed-loop direct current braking method, and the torque response speed is improved and the position static error is eliminated by carrying out closed-loop compensation on the angle of the braking current.

    本发明提供一种高压永磁直驱式提升机平稳悬停的控制方法,属于矿用提升机技术领域,包括:利用第一PI控制器对永磁同步电机的制动角度进行补偿,得到悬停角度补偿量;根据所述悬停角度补偿量计算悬停制动转矩,调整悬停角度补偿量,直到所述悬停制动转矩与负载转矩匹配,输出调整后的悬停制动角度;本发明通过电流闭环的直流制动法进行悬停控制,并通过对制动电流的角度进行闭环补偿来提高转矩响应速度和消除位置静态误差。
