| Abstract: | A composite control strategy of permanent magnet synchronous motor combined with sliding mode speed control and extended sliding mode disturbance observer was proposed. The new approximation law design was adopted by the sliding mode speed control, and the extended sliding mode disturbance observer could accurately estimate the inner parameters perturbation and external load interference. The realtime estimation of the integrated disturbance items in the control system through the system disturbance estimation link was realized, then the estimated value was used to do the feedforward compensation for the speed control link, and the active disturbance rejection control of the system was realized. The experimental results verify the validity and feasibility of the proposed control strategy. |
