Abstract
AbstractThis article focuses on the problem of fixed‐time position tracking of permanent magnet synchronous motors with uncertain parameters and load torque disturbance. Based on the fixed‐time stability theory, adaptive control, fuzzy control, and backstepping algorithm, a novel adaptive fuzzy fixed‐time controller is proposed. It is shown that the presented control scheme can guarantee that the tracking errorconverges to a small neighborhood of the zero and all the signals of the close‐loop system are bounded in the fixed‐time. At last, the theoretical analysis and simulation results verify the effectiveness of the developed control strategy.
