摘要
为提高制导炮弹控制系统性能,提出一种基于动态面控制的设计算法.通过建立具有"块严格反馈"的制导炮弹非线性状态空间模型,采用动态面控制算法进行全状态耦合设计.考虑到模型中的不确定项,将其视为未知有界干扰,并构造自适应律进行在线估计估计和补偿.仿真结果表明,该算法能快速无超调地跟踪指令信号,优于传统三通道独立设计的PID算法和自适应滑模控制算法,验证了其有效性.此外,在±50%气动摄动下,该算法仍能对指令的快速稳定跟踪,具有优越性和强鲁棒性.
Abstract
To improve the control system performance,this paper presents a scheme of the adaptive dynamic surface control algorithm for guided projectile control system design.Firstly,the so-called'block strick feedback'state-space model is established with the fully coupled and nonlinear form,and the full states coupling design is performed based on dynamic surface control algorithm.Then,the uncertainty terms are considered as the unknown bounded disturbances,and are estimated on-line through the constructed adaptive law.The effectiveness of the presented scheme is verified via the other different algorithms.Besides,under the±50%aerodynamic perturbations,the proposed scheme can track the commands solidly,which reflects the superiority and strong robustness.
