Abstract In some drive situations of high performance, the existence of inertia disturbance is an important factor to cause the servo system performance deterioration. An adaptive control method with anti-disturbance is proposed. Gradient algorithm is introduced to estimate system inertia on-line. And then according to the principle of pole assignment, regulate the parameters of the speed controller (proportional coefficient K_pω and integral coefficient K_iω of the speed loop) real-time by the estimated inertia adaptively. In this paper, the theoretical analysis is given in detail. Taking a surface mounted permanent magnet synchronous motor as the object, simulation and experiment of inertia identification and adaptation are carried out. The results prove that the proposed adaptive algorithm based on gradient identification is effctive.

Key words： Permanent magnet synchronous motor inertia identification gradient algorithm adaptation
