用于机械原理课程中对RRR结构的运动分析，可用于计算位移、速度、加速度(Courses for mechanical principle of the movement structure of the RRR analysis, can be used to calculate the displacement, velocity, acceleration)

说明：  蒙特卡罗模拟随机数是最好的方式，本程序设计在552nm脉冲后，再一左一右的657nm冷却脉冲，测试激发达到100 的概率，尤其考查蓝、绿及近红外波段(MATLAB 6.5 Monte Carlo simulation cool3.m This simulation cycles "num" number of atoms "steps" times, with a cooling sequence of a 657 nm cooling pulse from the right, then a 657 nm cooling pulse from the left, followed by a 552 nm quenching pulse. Then the sequence is repeated with cooling pluses first incident from the left. Switching the pulse direction order helps maintain symmetery in the resultant velocity distribution. The probability of quenching the excited state is no longer 100 , it is "percent" Random blue, IR, and green photon recoil kicks have been included in the simulation due to the quenching. )

This creates a trapezoid wave, similar to the built-in square function but with no duty cycle option

现有的PID参数优化方法往往难以同时兼顾系统对快速性、稳定性与鲁棒性的要求，本文针对这一缺陷，提出了一种多目标PID优化设计方法——在满足系统的鲁棒性的前提下，以超调量、上升时间和调整时间最小作为多目标优化的子目标，并将NSGA-Ⅱ与PGA相结合对其求解。该算法求得的Pareto最优解分布均匀，收敛性和鲁棒性好，决策者可根据实际系统的要求在Pareto解集中选择最终的满意解，这为快速性、稳定性与鲁棒性的权衡分析提供了有效的工具。仿真结果表明本文设计方法的有效性和优越性。()
