摘要
实时多处理器系统的动态调度算法一直是实时系统研究中的重要课题。该文首先介绍了实时多处理器动态调度的几种方法,并对这些方法进行了分析、对比和研究。然后针对水下航行器制导系统多任务特点,讨论了水下航行器制导系统的动力学、运动学模型及控制、导引方程,并对其任务进行详细划分。最后结合任务的偏序关系、运行时间及截止期,对水下航行器多任务模型进行了实时多处理器动态调度,给出最佳调度方案。
Dynamic scheduling algorithm for real-time muhiprocessor systems is an important subject in real-time system research.Several approachs are introduced for dynamic scheduling algorithm of real-time muhiprocessor,and are analyzed,contrasted and researched.The dynamic and kinematic model,control and guidance equations of underwater vehicle are discussed,which tasks are divided in details ,according to it＇s characteristics.Finally,dynamic scheduling for real-time muhiprocessor is applied to multi-task mode of underwater vehicle in terms of task＇s order,execution time and deadline,and the optimizatal scheduling is given.
