对于点检测分析和算例,方便大家学习和使用.(For point detection analysis and examples to facilitate them to learn and use.)

在某初教机的线性模型基础上，建立了飞机的纵向和横向传递函数，分析了模型参数的不确定性，通过使用MATLAB中的NCD模块对飞行控制系统及PID控制器等参数进行优化，设计出了飞机的自动驾驶仪高度保持和航向保持模式。这种方法既避免了复杂的计算和编程，又使系统具有较好的稳定，陛、动态性能和鲁棒性，克服了飞机模型参数随着高度和速度的变化（即模型参数存在不确定性）而需要按照多个不同高度和速度的飞行区域设计一系列控制器的缺点(early in a plane of the linear model, based on the aircraft's vertical and horizontal transfer function, Analysis of the model parameters of uncertainty, MATLAB through the use of the NCD Blocks flight control system and PID controller parameters for optimization, design of the aircraft's automatic pilot systems, and maintain a high degree course-keeping mode. This method not only avoids the complex calculation and programming, the system has good stability, Her Majesty, dynamic performance and robustness. overcome the aircraft model parameters with the height and speed of change (that model parameters uncertainty exists) and the need to not more than with the height and speed of regional flight controller design a series of shortcomings)
