【摘要】：為了研究某型飛機(jī)的結(jié)冰試驗(yàn),需要研發(fā)一套飛機(jī)空中噴水作業(yè)系統(tǒng)。飛機(jī)噴水桁桿控制系統(tǒng)是飛機(jī)空中噴水作業(yè)設(shè)備的重要組成部分,需要將桁桿穩(wěn)定在設(shè)定角度進(jìn)行噴水作業(yè)。由于繩索張力、桁桿系統(tǒng)氣動(dòng)力及重力的綜合作用,使得桁桿的控制變得復(fù)雜。針對(duì)飛機(jī)噴水桁桿系統(tǒng)進(jìn)行了數(shù)學(xué)建模分析,并利用線性二次型調(diào)節(jié)器(Linear Quadratic Regulator,LQR)進(jìn)行了控制器設(shè)計(jì)和控制參數(shù)的獲取。仿真結(jié)果表明,所設(shè)計(jì)的控制器不僅提高了桁桿系統(tǒng)的穩(wěn)定性,還有效改善了控制系統(tǒng)動(dòng)態(tài)響應(yīng)和魯棒性。
[Abstract]:In order to study the ice forming test of a certain type of aircraft, it is necessary to develop an air water jet operating system, which is an important part of the jet water spraying equipment. It is necessary to stabilize the truss rod in the water spraying operation at a set angle. The control of the truss rod becomes complicated because of the combined action of the rope tension, the aerodynamic force of the truss rod system and the gravity. The mathematical modeling analysis of the jet truss rod system of the aircraft is carried out. The linear quadratic regulator linear Quadratic regulator LQR) is used to design the controller and obtain the control parameters. The simulation results show that the controller not only improves the stability of the truss rod system, but also improves the stability of the truss rod system. It also improves the dynamic response and robustness of the control system.
