基于有限状态自动机的传感器管理方法

Sensor management method based on finite state automata

传感器管理是多传感器融合系统的重要组成部分。针对目前传感器出现故障时仍然缺乏对传感器资源管理的有效方法,提出一种基于有限状态自动机的传感器管理方法。首先,建立传感器管理控制策略的有限状态自动机模型,通过对可控制事件的非使能设定,描述不同控制策略;提出语言测度参数的递归估计方法与停止规则,并根据有限状态自动机模型产生语言的测度获得各种传感器控制策略的性能指标。实例分析结果表明:利用有限状态自动机模型能够辅助设计传感器故障控制策略,根据语言测度可以正确评价传感器控制策略。

Sensor management is an important component of multi-sensor fusion systems. Since there exists the lack of an efficient method for multi-sensor fault control of sensor management, a method of sensor manage- ment based on the finite state automata （FSA） is proposed. Firstly,different control strategies for sensor man- agement are modeled by the real language measure. The legal behavior of control strategy modeled by FSA can generate a partially ordered set of controlled languages. Then an identification method of the language measure parameters based on an FSA model is proposed. The language measure creates a total ordering on the perform- ance of the controlled languages. The experiment validates that FSA model can design sensor fault control strat egies, and the language measure can evaluate the performance of the different control strategies effectively.
