摘要
倾斜转弯控制技术的控制特点决定了倾斜转弯导弹成为一个强耦合的非线性时变系统,这为其控制系统设计增大了难度。将某型倾斜转弯导弹俯仰、偏航及滚动通道间的耦合作用看作是干扰,然后应用H∞控制理论设计导弹自动驾驶仪。简单有效的方法就是求解代数Riccati方程的正定解,从而可以构造系统的反馈增益矩阵,得到满足要求的反馈控制器,但评估信号的选取是一个关键。通过三通道控制系统联合仿真研究表明,该设计方法可行,设计的自动驾驶仪对倾斜转弯导弹控制效果好,能快速跟踪导引指令,满足设计指标。
The characteristics of BBT missile control system make BBT missile to be a nonlinear time-varying system with strong coupling,which adds more difficulties to the BBT missile system design.A method was proposed that regarded the coupling among the pitching,the yawing and the rolling channels as disturbance,and then applied H∞control theory to the missile autopilot design.By the positive definite solution of the Riccati equation,the gain matrix of the feedback system could be formed and the satisfying feedback controller could also be gained.In the solution procedure,the selection of the assessed signal is the key point.The simulation of system shows that the method proposed is feasible and effective.The autopilot which designed with it can follow the guidance signal fast and has a high quality performance.
