摘要/Abstract

摘要： 针对飞行仿真转台系统在实际运行中易受到外界干扰和非线性摩擦等的影响,提出了一种带有等价输入干扰(Equivalent Input Disturbance,EID)估计器的改进型近似微分复合控制策略,并给出了给定参数整定条件。采用等价输入干扰估计器对系统等效输入干扰进行补偿;利用改进型近似微分器构建数字前馈,改进型近似微分器可以精确地获取信号的速度信号与加速度信号,且对噪声具有一定的抑制能力,避免了传统差分法放大噪声的弊端。该复合控制策略提高了系统的跟踪精度和鲁棒性,仿真结果表明了该方法的有效性。

Abstract: In view of the problem that the interference and nonlinear friction sensitively effect on flight simulators, an improved approximation differential compound control strategy with Equivalent Input Disturbance (EID) estimator is presented. Moreover, the setting conditions based on given parameters was proposed. In the presented strategy, the EID estimator can compensate the equivalent input disturbance of the system. Furthermore, owing to the construction of the digital feedforward via the improved differentiator, the improved approximation differentiator is able to acquire accurately the velocity and the acceleration of the signal, and has an ability to inhibit the partial noise by use of the improved. It avoids the disadvantage of the traditional differential method, which causes the amplification of the noise. Thus, the presented compound control strategy can improve the tracking precision and robustness of the system effectively. The simulation results show the effectiveness of the proposed method.
