勒·柯布西耶是现代建筑运动的领军人物,他在早期作品中所表现出来的简约、纯粹的建筑思想促进了现代建筑的发展。而极少主义建筑思想兴起于20世纪下半叶。极少主义提倡简约、自然,消除繁琐的装饰,体现建筑最本质元素的元素。这与早期勒·柯布西耶所提倡的建筑哲学类似。本文以勒·柯布西耶早期建筑思想及其作品为切入点,探究其与"极少主义"的关系。

针对高超声速飞行器随机参数摄动的姿态控制问题,提出一种基于轨迹线性化和扩展卡尔曼滤波(extended Kalman filter,EKF)的预测滑模控制方法。首先,针对随机参数摄动的高超声速飞行器非线性模型,采用轨迹线性化方法建立线性时变误差调节模型。通过分析参数误差的统计特性,将统计信息以参数协方差矩阵的形式进行表示,并设计EKF对受扰误差状态进行滤波。然后,采用预测滑模控制方法设计误差稳定调节器,使系统快速趋于稳定。所提方法对随机参数摄动和非线性干扰都具有强鲁棒性。仿真验证了所提方法的有效性。
