| 中文摘要 |
| 针对飞行仿真转台中传统插值和前馈方法对系统性能的限制问题, 引入了完全跟踪控制策略. 论述了飞行仿真转台完全跟踪控制器的设计方法. 本文利用多速率采样系统的特性构造转台系统状态传递函数矩阵的精确逆矩阵, 从而避免了采用近似逆模型的传统方案以及插值带来的限制, 实现完全跟踪. 利用鲁棒内回路补偿器理论以及系统动态跟踪误差的解析式分析说明了该方法在实际系统中存在建模误差、干扰和噪声的情况下, 仍然能够保证系统的动态跟踪精度和良好的鲁棒性. 对实际系统进行了设计与实验, 结果证明了该方法的有效性.

| 英文摘要 |
| To deal with the performance limitations for the traditional interpolation and feedforward methods in flight simulator, we introduce the perfect tracking control(PTC) strategy, and study its application on the design of a flight simulator for perfect tracking. We make use of the characteristics of a multirate sampling system to build an exact inverse transfer function matrix model of the flight simulator for realizing the perfect tracking, preventing from the performance limitations brought about by the traditional approximate inverse transfer matrix model and the interpolation algorithm. By the robust internal-loop compensator theory, and based on the analytical expressions of the tracking errors, we prove that the proposed strategy ensures the system with desired tracking accuracy and excellent robustness, even in the existence of modeling errors and disturbances. Results in designing and experimenting in practical systems validate the proposed strategy. |
