Application of classic rating-monotonic scheduling algorithm in UAV engine test system

Modern unmanned aerial vehicle (UAV) engine testing has a wide range of high real-time requirements. Previous research based on non-real-time was unable to meet these test requirements. This paper integrate classic rate monotonic (RM) with the software systems for UAV engine test platform to satisfy the requirements. Besides, this paper analyzes the criterion of the classical RM algorithm schedulability and describes the design process of task set. The testing for the real schedulability of the tasks shows that the desired effect of system is achieved and the maximum hardware utilization reaches 93.8%, which meets the design requirements.
