This study conducts a thorough investigation of reliability control strategies for orbital Contactless Power Supply (CPS) systems in material handling applications. Existing literature predominantly utilizes a simplified purely resistive load model, which overlooks the impact of the inductive characteristics of motors in actual operating conditions. This often leads to suboptimal control strategy performance in practical applications, necessitating the use of large capacitors at the receiving end to ensure output stability. To address this issue, this paper introduces a more realistic inductive load model and compares the performance of traditional proportional-integral (PI) control systems with novel control strategies. The focus is on assessing the stability and reliability of these strategies under complex electrical disturbances. The results indicate that the new control strategies significantly enhance the system's resistance to electrical disturbances, thereby substantially improving the industrial reliability of the entire handling system. These findings have important theoretical and practical implications for the design and implementation of orbital wireless power transmission systems.
