                                參數整定找最佳，從小到大順序查.
　　            先是比例后積分，最后再把微分加.
　　            曲線(xiàn)振蕩很頻繁，放大倍數要放小.
　　            曲線(xiàn)漂浮繞大灣，放大倍數往大扳.
　　            曲線(xiàn)偏離回復慢，積分時(shí)間往下降.
　　            曲線(xiàn)波動(dòng)周期長(cháng)，積分時(shí)間再加長(cháng).
　　            曲線(xiàn)振蕩頻率快，先把微分降下來(lái).
