摘　　要：为了减小多管火箭在发射过程中定向管振动对火箭弹起始扰动的影响,考虑多管火箭的噪声干扰,基于多体系统传递矩阵法建立了多管火箭动力学模型,在模态空间下设计了H2最优控制器控制定向管振动,进行了数值仿真,并把H2最优控制器与PD控制器进行了仿真对比,结果表明,采用H2最优控制器的系统不但具有良好的瞬态和稳态性能,而且具有较好的抗干扰能力,能有效地抑制噪声干扰,增强了控制系统的鲁棒性能。To reduce the influences of vibration of launch tube on launching rocket at its initial disturbance stage in Multiple Launch Rocket System（MLRS） were studied in the paper.In practical engineering there are noises during vibration control of MLRS.The dynamical model of MLRS based on transfer matrix of multi-body system was built.In independent modal space,H2 optimal controller is designed to control vibration of launch tube of MLRS.Numerical simulations of dynamical response of MLRS under control have been carried out.PD controller is contrasted with H2 optimal one.The numerical results indicate that H2 optimal controller enables the system to have good transient state and stable state performance,thus better resistance to disturbance.It can effectively curb the noise interference,strengthen the system robust performance.
