영구자석동기모터의 외란 관측기 기반의 비선형 속도 제어기

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.

In this paper, we develop a sliding mode controller that uses a nonlinear sliding manifold for the permanent magnet synchronous motor. The proposed controller makes sure that both currents and velocity tracking error converge into equilibria. Nonlinear sliding manifold consists of current dynamics and nonlinear functions which are designed with velocity tracking error and its integrated term. The nonlinear functions are designed to guarantee that velocity tracking error converge into zero. The closed-loop stability is proven by Lyapunov theory. The effectiveness of proposed method is demonstrated by numerical simulation results.
