摘  要:某型导弹随动系统动力学模型的复杂性及客观环境中的干扰因素,使传统单一模式的控制难以达到预定的要求,有必要寻求鲁棒性强且大误差可控的控制策略.针对模型参数及外界干扰的不确定性,在对该型导弹随动系统的控制方式进行分析研究的基础上,设计一种基于模拟退火算法(SA)优化的模糊控制和鲁棒PID控制的复合控制方法,并用MATLAB软件进行数值仿真.仿真结果表明,复合控制系统的各项性能都比原系统有显著提高.For the complexity of dynamic model in the follow-up system of a kind of missile and the interference objectively available in the environment, the conventional single-mode control cannot meet its predetermined requirements, so that a control strategy with strong robustness and error-controllability is to be sought. Taking the uncertainty of model parameters and external disturbances into consideration and based on the analysis and investigation of the control mode of this kind of missile, a compound control method based on the both of optimized fuzzy control with simulated annealing algorithm and robust PID control was devised and numerically simulated with the software MATLAB. The simulation result showed that all items of performances of the compound control system were remarkably improved when compared with the original control system.
