摘要
针对制导炮弹周期性滚转产生的俯仰和偏航通道之间的交叉耦合效应,采用前馈补偿法解耦结合PID控制器设计了解耦控制算法。建立自旋制导炮弹数学模型,求解得到俯仰和偏航方向的传递函数,利用相对增益判定耦合度并采用前馈补偿法进行解耦,运用PID控制结合前馈补偿器设计制导炮弹的解耦控制系统,该方法简化了控制器,实现了对制导炮弹强耦合系统的解耦。经数值仿真分析可知,所设计的控制方法在强耦合和参数摄动下,具有快速响应能力、较高指令跟踪精度和强鲁棒特性,实现了系统解耦,满足系统性能要求。
Abstract
Aiming at the cross-coupling effect between pitch and yaw channels due to periodic rolling of guided projectiles, we designed a decoupling control algorithm by using feed-forward compensation method together with the PID controller.A mathematical model of the spin-guided projectile was established, and the transfer functions of pitch and yaw direction were obtained.The degree of coupling was determined by using the relative gain, and feed-forward compensation method was used for decoupling.PID control was used together with feed-forward compensator for the design of a guided projectile decoupling control system.This approach simplified the controller, and decoupled the strong coupling system guided projectile.The numerical simulation analysis shows that the control method has rapid response capability, high command tracking accuracy and robustness characteristics under the strong coupling and parameter perturbations.This method achieves the decoupling control system and can satisfy the system performance requirements.
