To address the issues of torque ripple and insufficient anti-disturbance capability in induction motors under low-speed high-torque operating conditions, this paper proposes a high-performance Field-Oriented Control (FOC) scheme incorporating Linear Active Disturbance Rejection Control (LADRC), based on the domestic GD32 microcontroller. The system adopts a dual closed-loop structure for speed and current, integrates rotor flux linkage and slip angular velocity calculation modules, and introduces voltage feedforward compensation to improve dynamic decoupling performance. To further enhance the anti-disturbance performance at low speeds, LADRC is employed to replace the traditional PI controller as the speed loop regulator, enabling real-time estimation and compensation for internal and external disturbances of the system. On the hardware side, data acquisition is optimized using differential isolated current sampling and a DMA transmission mechanism, ensuring the real-time capability and accuracy of current measurement. On the software side, the GD32"s FPU is utilized for accelerated computation, and a simplified SVPWM strategy is adopted to reduce the computational burden. Results show that, compared to traditional VVVF control, this system significantly improves the motor"s load-bearing capability at extremely low speeds. In the frequency band below 5 Hz, the LADRC strategy reduces the settling time by 22%–26% compared to the PI strategy, and the speed drop during load transients is suppressed within 0.2 r/s, verifying the system"s superiority in low-speed high-torque performance and strong anti-disturbance capability.
