增量式PID控制算法Matlab仿真程序 设一被控对象G（s）=50/(0.125s^2+7s),用增量式PID控制算法编写仿真程序（输入分别为单位阶跃、正弦信号，采样时间为1ms，控制器输出限幅：[-5,5],仿真曲线包括系统输出及误差曲线，并加上注释、图例）。(Incremental PID control algorithm Matlab simulation program to set up a controlled object G (s) = 50/(0.125s ^ 2+7s), with incremental PID control algorithm simulation program written (unit step input, respectively, sinusoidal signal sampling time is 1ms, the controller output limiter: [-5,5], including simulation system output and error curve curves, plus notes, legend).)

说明：  模糊算子5种方法，应该有点用吧。能求出综合评价(There are 5 ways of using fuzzy operators. We can figure out the comprehensive evaluation)

：给出了一种提取特征点的新方法和合理的特征不变量。该方法根据三角不等式原理利用第三边与另 外两边之和的比值大小来确定角点，以特征点和它相邻的两个特征点所形成的两条直线的夹角正切值以及三角形 第三边与另两边和的比值作为特征不变量。这种特征提取的方法简单，并且由于扩大了模板取值范围，使识别效果受特征点漏检的影响较小。实验表明，该方法不仅简便，而且效果良好。(: In this paper, a new feature point extraction method and the characteristics of rational invariants. The method is based on the principle of triangle inequality with the use of the third side and both sides of the ratio of the size to determine the Corner to feature point and its two adjacent feature points formed by the angle between two tangent linear and the third triangle on both sides and edges with another feature of the ratio as a variable. This feature extraction method is simple, and as a result of the expansion of the scope of the template values to identify the effect of feature points by the impact of smaller undetected. Experiments show that the method is not only simple, but effective.)
