VB模拟景深近处清淅远处模糊的图片合成效果，将两张照片合成，最终形成照片高景深效果。 　　合并图片原理：在模糊区域，某一像素点“0”的值应是周围24个像素点失焦时弥散圆的迭加。由于四个角因距离较远，贡献较少，应取较小的权值，这25个点的均方差应较校如果这是清晰区域，则25个点的均方差应较大。对于四周边缘区域，只能取到部分，对于同一种颜色，清晰区的鲜艳一些。

本游戏的主角是个小球，玩家通过按右键的时间长短来决定小球的初始速度，当按动左键时小球启动，小球在运动过程中将受到磨察力的作用，速度将减慢最终停止，小球停止的位置距离右边红色墙壁的距离（距离越近成绩越高）及小球在运行过程中与墙壁碰撞的次数（次数越多成绩越高）将决定玩家的最终成绩，按任意键程序将把当前成绩与存放在mc.txt中的历史成绩比较，给玩家以平价，并将当前成绩保存在mc.txt中。游戏有两个界面第一个界面是游戏场景，其中有三个参数，由左至右依次为“DIS”最终离右边墙的距离，“BUMP”小球在运行过程中碰墙的次数，“SPEED”小球的运行速度。第二个场景是成绩平价界面，根据玩家成绩给以相应的平价 。另外，由于机器配置的不同可能会出现速度上的迥异。-the protagonist of this game is a small ball, players adopted by the right to determine the length of time the ball"s initial velocity, when pressed button at the start of small ball, the ball movement in the process of grinding reviewer will be the role of power, speed will slow down eventually stopped, the ball stopped at a location away from the right side of the red walls of the distance ( the more recent results from the higher) and the ball in the course of operation and the number of collisions walls (the more the number of higher performance) will determine the ultimate success players by arbitrary procedures will bond with the current performance mc

说明：  传统的永磁同步电机(Permanent Magnet Synchronous Motor, PMSM)自抗扰调速 系统往往存在可调参数多且整定复杂的问题，利用滑模控制方法(Sliding Mode Control,SMC)对自抗扰控制(Active Disturbance Rejection Control, ADRC)结构进行改进，设计了PMSM 调速系统的滑模自抗扰速度控制器和电流控制器。将滑模控制方法引入自抗扰控制结构中，将自抗扰控制中的扩张状态观测器和非线性误差反馈控制律进行优化，在保留自抗扰原有抗扰性能的基础上，简化了参数整定，提高了系统的响应速度和鲁棒性，利用李雅普诺夫理论证明了控制器的稳定性。仿真结果验证了该方法的有效性。(The traditional permanent magnet synchronous motor (PMSM) ADRC system often has many adjustable parameters and complex setting. Using the sliding mode control (SMC) to improve the structure of ADRC (active disturbance rejection control, ADRC), the ADRC speed controller and current control of PMSM are designed Manufacture. The sliding mode control method is introduced into the ADRC structure. The extended state observer and the nonlinear error feedback control law are optimized. On the basis of retaining the original ADRC performance, the parameter setting is simplified and the response speed and robustness of the system are improved. The stability of the controller is proved by using Lyapunov theory. The simulation results verify the effectiveness of the method.)
