INTELLIGENT CONTROL OF ELECTROHYDRAULIC SERVO LOADING SYSTEM FOR VARIABLE-SWEEP AIRCRAFT WING

变后掠机翼加载控制系统是一类复杂系统,具有非线性、弱阻尼、强干扰、以及刚性部件和弹性部件互相关联的特征。系统控制的难点表现在:当系统缺乏阻尼的情况下稳定振动、抑制关联干扰,并使得系统具有较高的加载控制精度。 本文给出互相关联电液加载系统智能控制具有优良的动态性能和很强的鲁棒性。

The final testing study of an intelligentcontrol of the electrohydraulic servo loading system for variable-sweepaircraft wing is presented. The loading system is characterized by nonlinearity, weak damping, strong disturbance, and interconnection of rigid and elastic parts. The tasks of stabilizing the persistent oscillation in the absence of damping, rejecting disturbance and loading with high accuracy pose difficult control problems. A simple and effective intelligent controller is proposed in the paper. The intelligent controller deal with situations that involve adjusting control parameters and selecting dynamical compensators in the face of changes in the control environment. The results of real test show that the intelligent control system has excellent dynamic performance and better robustness.
