| 摘 要： | 针对远程制导炮弹动力学模型多输入、多输出、多约束、非线性和快时变的特点,基于模型预测控制理论,设计了一种组合型非线性预测控制器.此控制器综合了2种非线性模型预测控制方法,一种方法以序列二次规划为在线优化算法求解最优控制律,另一种方法具有解析形式控制律.2种方法的合理组合克服了前一种方法的控制延迟和后一种方法没有考虑约束的缺点.将设计的控制器用于某制导炮弹滑翔段控制,仿真结果表明,该控制器控制效果较好.

| Abstract: | Aiming at the characteristics of multiple-input,multiple-output,multiple-constraint,nonlinear and fast time-varying of dynamic equations for extended-range guided projectile,a combined nonlinear predictive controller was proposed based on model prediction control theory.The controller brings together two kinds of nonlinear prediction control methods.One method takes sequential quadratic program as online optimization algorithm to solve optimal control law,and the other method is provided with analytical con... |
