摘要：

Attaining precise and dynamic speed control is pivotal for the efficient sensorless operation of permanent magnet synchronous motors. Addressing the challenge of parameter mismatch within the cascaded control structure of these motors, which results in diminished dynamic performance and increased static deviation, this paper introduces a speed-current single-loop control method for permanent magnet synchronous motors based on non-singular terminal sliding mode control. To begin, a second-order mathematical model of the motor under parameter disturbances is analyzed and derived. To suppress system disturbances arising from parameter mismatches, a cascaded extended state observer is established. A ultra-local model of the motor is then derived based on the mathematical model, and an adaptive non-singular fast terminal sliding mode controller is designed. The proposed method aims to optimize dynamic performance, steady-state accuracy, and system robustness. Finally, a rigorous stability analysis has been conducted for the proposed composite strategy. The feasibility and effectiveness of this approach are verified through comparative experiments with PID and sliding mode control (SMC).
