The invention discloses a permanent magnet motor flexible tether tension peak-to-average ratio suppression control strategy which is applied to the technical field of flexible transmission driving control. State feedback of the moving speed of the target object is introduced, and steady-state errors caused by load displacement to tether tension are compensated. In practical application, a motor driving controller is difficult to directly obtain the motion speed information of a target object, so that the realization method adopts state observation of the speed of the target object, realizes state feedback under the condition that the speed information of the target object cannot be directly obtained, and provides a basic principle and a realization scheme of the method. The provided state observer can well track the speed of a target object within an error allowable range, and meanwhile tension dynamic response is stable under the action of state feedback control. 本发明公开了一种永磁电机柔性系绳张力峰均比抑制控制策略，应用于柔性传动驱动控制的技术领域。
