Key Points

To develop an integrated framework combining controller design and digital task scheduling that dynamically adjusts task execution periods without compromising physical system stability.
Permitted task frequencies and periods to vary flexibly within bounded ranges that preserve critical control dynamics and stability.
Formulated an optimization algorithm to determine optimal task frequencies under constrained computing resources.
Applied the integrated scheduling framework to scenarios involving resource limitations, failure recovery, and system reconfiguration.
Resolved schedulability bottlenecks by treating task periods as tunable parameters rather than rigid constraints.
Enhanced overall control system performance and maximized hardware utilization relative to traditional isolated design pipelines.
Established adaptable scheduling mechanisms that support dynamic system reconfiguration and failure recovery during real-time operations.
