这个程序是基于matlab的计算工件粗糙度的轮廓算术平均偏差Ra的值。里面有例程，还有详细的代码注释，希望对各位有所帮助，代码段还有不完善的地方，运行时间过长，会报错，但是逻辑是没有问题的，日后再改进大家可以基于此来书写新的程序，算是抛砖引玉吧(This procedure is based on the calculation of the value of matlab workpiece contour arithmetic average roughness Ra of deviation. There are routines, as well as detailed code comments, you would like to help, there are imperfections in the code segment, at a later improvement, but logic should be no problem, we can be written based on this new program, regarded puts it)

四旋翼无人机SIMULINK建模，PSO_SA优化PID参数 reverse.m 作用：将History表中的string形式的key值转换为赋给九个全局变量temp00， ... ,temp08运行sum1.slx，可以直接观察此组参数的波形。 History 作用：映射表，将一组参数（temp00, ..., temp08）映射到这组参数的ITAE指标。 trojectory.m 作用：定义一条路径并进行路径压缩，通过不断向sum.slx传递位置参数，控制无人机运动，并接受无人机运动过程，做出无人机运动位置图像。 sum1.slx 作用：从外部接受一组位置关系（x,y,z）,模拟无人机由原点(0,0,0)运动到该位置并保持稳态这个过程中无人机的位置变化，并向外部反馈。 PSO_3D.m 作用：调用sum3D.slx，通过PSO得到内循环最优解的参数。 sum3D.slx 作用：获取.m文件中设置好的全局变量的值，模拟内循环三个角度的变化。 PSO_History.m 作用：调用sum9D.slx，通过PSO得到外循环最优解的参数，此过程已被History表优化。 PSO_SA.m 作用：调用sum9D.slx，通过PSO得到外循环最优解的参数，此文件在PSO_History.m基础上被模拟退火算法优化(Four rotor UAV SIMULINK modeling, PSO_SA optimize PID parameters)
