基于复合校正的主动杆执行机构控制策略研究

Research on Control Strategy of Active Side-Stick Actuator Based on Compound Correction

主动驾驶杆装置是现代先进战斗机的一个关键装置,对其主要部件执行机构进行科学有效的控制尤为重要。针对如何解决主动杆执行机构存在多余力以及抗干扰能力差的问题,首先设计了基于"电流、转速双内闭环+力外环"的力加载三闭环控制系统,并建立了其数学模型;然后分析了多余力存在的原因,设计了按扰动补偿的复合校正系统;最后利用Simulink平台进行了三闭环控制系统与复合校正系统的仿真分析与对比。结果表明设计的复合校正系统有效抑制了多余力,明显提高了系统的抗干扰能力。为主动杆执行机构提供了抗干扰能力较强的控制策略,为进一步的研究提供了参考。

Active Side-stick(ASS)device is a key device of modern advanced fighters,and its actuator is one of the most important parts.It is particularly important to control the actuator scientifically and effectively.In order to solve the problem of extraneous force and poor anti-interference ability of ASS actuator,a force loading three closed loop control system based on“current and speed double inner closed loop+external force loop”is designed,and its mathematical model is established.Then the reason for the existence of superfluous force is analyzed and a perturbation-compensated compound correction system is designed.Finally,the simulation analyses are carried out by using the Simulink platform,and comparison research of the three closed loop control system and the compound correction system are conducted.The results show that the designed compound correction system effectively suppresses the superfluous force,and significantly improves the anti-interference ability of the system.This paper provides a strong anti-interference control strategy for the ASS actuator,and the work in this paper provides a reference for further research.
