基于自主飞行的小型无人机动力自适应模糊控制

An Motive Adaptive Fuzzy Control for an Engine of the RPV Based on Independent Flight

针对传统无人机动力系统控制的局限性 ,提出小型无人机动力自适应模糊控制策略。在飞行控制计算机内建立发动机工作点的自适应模糊控制器 ,同时控制发动机油门和风门 ,并将其融进二维查询表中 ,利用传感器获取当前的发动机工作状态信息 ,通过软件方法进行查表 ,经简单的因子换算即可获取精确的输出控制量 ,实现对发动机的闭环监控。

Aiming at the limitation of the traditional RPV dynamic control system, an adaptive fuzzy control strategy of the RPV engine is put forward. We produce an adaptive fuzzy controller which can control wind-gate and oil-gate for the working points of the RPV engine in the flight control computer and put it into a two dimension inquired table. After getting present information on the state of the engine by a sensor, we inquire the table by software, at the same time we can get the accurate out-put controlled variable simply by transiting factors. In this way we can achieve the closed-loop control of the engine.
