Future aviation power exhibits characteristics such as wide-range multi-mode variable cycle regulation and cross-domain multi-objective control requirements, driving the next-generation control systems towards distributed, more-electric, hybrid-electric, intelligent, and proactive safety directions. Addressing the current issues of deficiency in collaboration between control and diagnostic tasks in distributed systems, high dependence on physical redundancy and conservative margins for safety, and performance bottlenecks with traditional algorithms, this paper proposes a more-electric distributed control system solution based on a dual-variable cycle engine prototype, along with an integrated approach to distributed control and diagnostics under an active safety architecture. The aim is to achieve organic synergy between proactive fault-tolerant direct performance control and hierarchical diagnostic strategies. Based on on-board performance and redundancy observation units, it enables performance estimation, stability margin estimation, and analytical redundancy of the control system, and through intelligent learning, it manages baseline models throughout the lifespan and on-board adaptive model corrections. The paper introduces a multi-scale information fusion-based direct performance active stabilization control algorithm, integrating hierarchical diagnostic strategies to achieve intelligent loop switching and analytical redundancy switching, ensuring system safety while fully unleashing performance potential. Finally, the effectiveness of the proposed method is validated through a distributed hardware-in-the-loop (DHIL) platform.
