针对空间探测系统中傅里叶变换光谱仪(FTS)在时变参数和非线性动力学条件下,对所需光程差速度进行高精度跟踪的问题,提出了一种新的FTS跟踪方法。提出了一种基于特征模型的自适应离散滑模控制方法。ADSMC的设计包括特征建模、基于特征模型的离散滑模控制和不确定系数的估计。文中还对ADSMC的稳定性进行了分析。仿真和实验结果表明,所提出的基于特征模型的ADSMC可以实现高精度控制的迈克尔逊干涉仪为基础的FTS。所提出的ADSMC的显着优点是它的鲁棒性和更好的控制性能的外部干扰和内部参数不确定性的系统。
This paper aims to guarantee high-precision tracking of the desired optical path difference velocity for a Fourier transform spectrometer (FTS) in a space exploration system with time-varying parameters and nonlinear dynamics. A novel characteristic model-based adaptive discrete-time sliding mode control (ADSMC) scheme is proposed. The design of the ADSMC includes characteristic modeling, characteristic model-based discrete-time sliding mode control, and the estimator of the uncertain coefficients. The stability analysis of the ADSMC is also given in this paper. Simulation and experimental results demonstrate that the proposed characteristic model-based ADSMC can achieve high-precision control over a Michelson interferometer-based FTS. The significant advantages of the proposed ADSMC are its robustness and better control performance over the external disturbance and internal parameter uncertainty of the system.
