常规PID、Smith预估补偿、改进的Smith、双控制器控制和内模的Simulink仿真图(Conventional PID, Smith, forecast compensation, the improved Smith, double control and internal model controller of Simulink simulation diagram )

这个程序演示了如何应用耦合结构空气动力问题，通过Matlab编程，分析了飞行器机翼颤振等问题。(This model demonstrates how to implement a coupled structural-aerodynamic problem. The wing, otherwise rigid, is allowed to pitch and plunge. The motion of the wing is defined using SimMechanics blocks. The aerodynamic model is a simple, quasi-steady formulation. Dynamic pressure is manipulated by varying the Mach number & Altitude. You can also vary the CG location of the wing by double clicking on the picture of the BACT subsystem. The structural, mass, and aerodynamic properties all come from the following "Modeling the Benchmark Active Control Technology Wind Tunnel Model for Application to Flutter Suppression" by Martin R. Waszak of NASA Langley. Automatic flutter detection is implemented via a state-machine in Stateflow. )

求解含有有限个变量的函数，维数可以是1000甚至上万维 都可以(Solving function contains a finite number of variables, dimensions can be 1000 on the World Wide Web can be even)

画出直方图，并将该直方图均衡化，以达到图像画面均匀。(Draw the histogram and the histogram equalization in order to achieve uniformity of the image screen.)

关于重金属污染应用matlab做图,并有表明功能区划分和污染程度的高低.(On the application of heavy metal pollution matlab to do the diagram, and show that the level of function zoning and pollution levels.)

《node入门》是一本较好的入门级教材，本人起初也使用，通俗易懂。希望对大家有所帮助。("Node Getting Started" is a good entry-level textbook, I first use, easy to understand. We want to help.)

数学实验中的最速落径问题 A,B是不在一条铅垂线上的两点，在链接A,B两点的所有光滑曲线中，找出一条曲线，使得初速度为零的质点，在重力的作用下，自A点下滑到B点所需的时间最短 (Mathematical experiment steepest drop Path problems A, B is not a vertical line of two points, the link A, B two points in all the smooth curve, to find a curve, the initial velocity of the particle is zero, gravity role, and since the point A to B points decline in the time required for the shortest)

贪婪随机自适应搜索法(GRASP)，使用随机化的最小最小完成时间算法来产生问题的初始解,再通过变邻域下降算法来改进这个解。(Greedy randomized adaptive search method (GRASP), the minimum use of randomized algorithm to generate the minimum completion time of the initial solutions of the problem, and through the variable neighborhood descent algorithm to improve the solution.)
