摘要/Abstract

摘要： 针对飞机舵机电液负载模拟器在工作过程中出现系统稳定性差、加载精度低、响应速度慢等问题,提出了采用最优二次型理论与改进型前馈补偿相结合的控制方法。该方法基于最优二次型理论设计最优控制算法优化系统结构特性,再将液压缸的活塞位移指令信号作为前馈补偿控制的输入,设计改进型前馈补偿控制器。仿真结果表明,该控制方法不仅能够显著提高飞机舵机电液负载模拟器的动态性能,而且可以有效抑制多余力干扰。

Abstract: Aiming at the problems of low stability, low loading precision and slow response of the servo hydraulic load simulator, a control method based on the combination of the optimal quadratic theory and the improved feedforward compensation is proposed. This method is based on the optimal quadratic theory to design the optimal control algorithm to optimize the structural characteristics. The hydraulic cylinder piston displacement signals are used as the input of feedforward compensation control to design improved feedforward compensation controller. The simulation results show that this control method can not only improve the dynamic performance of the aircraft rudder electro-hydraulic load simulator, but also can effectively eliminate the interference.

Key words: aircraft rudder electro-hydraulic load simulator, surplus torque, optimal quadratic form theory, improved feed forward compensation
