飞机喷水桁杆控制系统优化设计仿真

Optimize Design and Simulation of Aircraft Spray Pole Control System

为了研究某型飞机的结冰试验,需要研发一套飞机空中喷水作业系统。飞机喷水桁杆控制系统是飞机空中喷水作业设备的重要组成部分,需要将桁杆稳定在设定角度进行喷水作业。由于绳索张力、桁杆系统气动力及重力的综合作用,使得桁杆的控制变得复杂。针对飞机喷水桁杆系统进行了数学建模分析,并利用线性二次型调节器(Linear Quadratic Regulator,LQR)进行了控制器设计和控制参数的获取。仿真结果表明,所设计的控制器不仅提高了桁杆系统的稳定性,还有效改善了控制系统动态响应和鲁棒性。

Spray pole control system is important part of air spray task system, which is needed to work at setting angle. Control for pole system become difficult because string force, aerodynamic force of pole system and gravitation are effect together. In the paper, math models were built and analyses were processed for the pole system. A control- ler was designed based on Linear Quadratic Regulator （LQR）. Stabilization was enhanced based on the designed controller and simulation results were shown to have good dynamic responses and robustness.
