In this paper, we propose a disturbance observer (DOB) based nonlinear velocity controller for permanent magnet synchronous motors (PMSMs). The proposed method consists of DOBs and a velocity controller. The DOBs are developed to estimate the disturbances in velocity and current dynamics without the use of the derivative of the measured signals. The observer gains are chosen using frequency analysis. Using Lyapunov theory, the velocity controller is designed for velocity tracking and disturbance compensation. Closed-loop stability is proven using the input to state stability property. The effectiveness of the proposed method is demonstrated by simulations. © ICROS 2019.
