摘要 采用传统方法对制导炮弹转速方向进行估计时,推导过程复杂,花费时间较长,针对该问题设计了一种制导炮弹塑料弹带转速方向非线性估计模型。首先通过具有解析控制律的非线性估计控制方法获取非线性估计控制解析形式最佳控制量,结合制导炮弹转速方向动力学模型,设计制导炮弹塑料弹带转速方向非线性离散控制器模型;然后运用基于反馈线性化理论的解耦控制方法获取解耦控制律,在此基础上通过线性外推法对某时刻的输出指令进行估计,构建离散滑膜控制器模型。分析实验结果可知,采用该非线性估计模型对制导炮弹转速方向进行估计时,响应时间维持在0.5s左右,控制响应较快,说明所提模型控制性能高,具有一定的实用价值。 Aiming at complex and time consuming of the derivation process to estimate the rotational speed direction of guided projectile in traditional method,it introduces a nonlinear estimation model for rotational speed direction of plastic belt of guided projectile.The nonlinear estimation control method with analytic control law is used to obtain the analytic optimal control variable of the nonlinear estimation control.The nonlinear discrete controller model of the plastic belt rotational speed direction of the guided projectile is designed based on the rotational speed direction dynamics model of the guided projectile.The decoupling control method based on feedback linearization theory is used to obtain the optimal control variable.Based on the decoupled control law,the output command of a certain time is estimated by linear extrapolation method,and the discrete sliding mode controller model is constructed.The experimental results show that the designed model can effectively estimate the rotational speed direction of the guided projectile,and the speed is about 0.5s,and the control response is fast.It shows that the control performance of the proposed model is high,and has certain practical value.
