| 摘 要： | 基于模型跟踪全局滑模控制理论,针对STT导弹设计一种新型滑模控制算法。建立STT导弹纵向通道的数学模型及相应误差模型,给出模型完全跟踪的条件,根据控制系统的动态设计指标和稳定性要求,分别设计滑态参数阵和全程滑态因子,并分析算法的稳定性。仿真结果表明:当导弹气动参数时变且大范围摄动时,设计的控制系统仍具有良好的动态性能和强鲁棒性。

| Abstract: | Based on model tracking global sliding mode variable structure control （GSVSC） theory, a new sliding mode variable structure control algorithm of STT missile was designed in this paper. The model and the error model of the plant were established, the design method of sliding mode parameter matrixed, global sliding mode factor and switching function were put forward according to dynamic and stability index. The stability of the algorithm was also analyzed. The simulation results showed that when the dynamic parameters of the missile were time-varied with perturbation, the control system designed also had good dynamic properties and strong robustness. |
