Traditional identification method for permanent magnet synchronous motor could not always guarantee the satisfying accuracy, thus an improved online identification method based on recursive fixed memory least square method is proposed in this paper to solve the problem above. A full rank equation is firstly constructed based on the q-axis voltage model under steady state. Then the recursive fixed...
In this paper, the adaptive robust control (ARC) algorithm is proposed for tracking control of the electric cylinder position. According to the analysis of the working principle of the electric cylinder servo system, the model of the system is established on the modified Lugre friction model, and single observer is designed for calculating friction as well. Then the ARC controller and adaptive law...
