基于固定时期的 abort 策略,安排方法论的新奇预兆的控制被建议高效地解决溢出问题。由在预言序列把最近的控制值用于控制目的,新策略被期望为更好的性能优化控制系统并且还保证所有任务的 schedulability 在下面溢出。有 p 时期的即时系统的 schedulability 溢出被分析,并且相应稳定性标准也被给。模拟结果证明新途径能与的相比改进控制系统的表演常规放弃策略,它能减少 overshoot 并且调整时间以及保证 schedulability 和稳定性。
Based on the abort strategy of fixed periods, a novel predictive control scheduling methodology was proposed to efficiently solve overrun problems. By applying the latest control value in the prediction sequences to the control objective, the new strategy was expected to optimize the control system for better performance and yet guarantee the schedulability of all tasks under overrun. The schedulability of the real-time systems with p-period overruns was analyzed, and the corresponding stability criteria was given as well. The simulation results show that the new approach can improve the performance of control system compared to that of conventional abort strategy, it can reduce the overshoot and adjust time as well as ensure the schedulability and stability.
