To address the stringent robustness requirements of electromagnetic compatibility (EMC) test equipment for automotive steering systems in complex environments, this paper proposes a novel active disturbance rejection control strategy that integrates fuzzy control with a super-twisting sliding mode algorithm. Building upon the linear active disturbance rejection control framework, the super-twisting sliding mode algorithm is incorporated into both the extended state observer and the error feedback control law, thereby enhancing the system's dynamic response and disturbance rejection capability. Furthermore, fuzzy control is employed to dynamically optimize key parameters in real time. Matlab simulations demonstrate that the proposed method achieves faster response and stronger anti-interference performance compared to traditional linear active disturbance rejection control. Additionally, to cope with complex EMC environments, an improved power filter is designed to suppress noise. Finally, EMC anechoic chamber tests validate that the developed equipment exhibits high testing accuracy and strong robustness, meeting the testing requirements for vehicle steering systems.
