基于遗传算法的主动悬架模糊控制，通过遗传算法来优化模糊控制的隶属度函数，以此来优化悬架的垂直加速度的方均根(Fuzzy control of active suspension based on genetic algorithm and membership function of fuzzy control are optimized by genetic algorithm to optimize the mean square root of vertical acceleration of suspension.)

说明：  给定n种物品和一个背包,物品i的重量是Wi,价值是vi,被包容量是C,应该如何选择装入被包的物品,使得装入背包中物品的总价值最大?对于每种物品i,只有两种选择,装入或者不装入. 输入:第一行两个正整数n(物品数)和C(容量) 第二行n个正整数n,表示物品价值 第三行n个正整数n,表示物品重量 输出:第一行表示总价值 第二行n个数(0/1),0表示物品不装入,1表示装入 例如, 输入: 5 10 6 3 5 4 6 2 2 6 5 4 输出 15 1 1 0 0 1 (Species of a given n items and a backpack, the weight of item i is Wi, the value of vi, was packet capacity is C, should be how to choose a package of items to be loaded, the backpack load in the largest total value of goods? For each item i, there are only two options, loaded or not loaded. Input: the first line of the two positive integer n (the number of items) and C (capacity) of the second line of n positive integer n, that the value of the third line of n positive integer n, that the weight of output: the total value of the first line of the second line, said n number of (0/1), 0 that the items do not load, that load 1 for example, enter: 5,106,354,622 6 5 4 output 15 1 1 0 0 1)

一个典型闭环控制系统的组成是很复杂的。通常都由给定系统输入量的给定元件、产生偏差信号的比较元件、对偏差信号进行放大的放大元件、直接对被控对象起作用的执行元件、对系统进行补偿的校正元件及检测被控对象的测量元件等典型环节组成。而控制系统设计则是根据生产工艺的要求确定完成工作的必要的组成控制系统的环节，确定环节的参数、确定控制方式、对所设计的系统进行仿真、校正使其符合设计要求。同时根据生产工艺对系统的稳、快、准等具体指标选择合适的控制元件。自动控制原理的时域分析法，根轨迹法，频域分析法，以及各种补偿（校正）装置的作用及用法，能够利用不同的分析法对给定系统进行性能分析，能根据不同的系统性能指标要求进行合理的系统设计，并调试满足系统的指标。(A composition of the typical closed-loop control system is very complicated. Usually produced by a given component to given system input, resulting in a comparison of the deviation signal component, and the amplified error signal amplification components directly to the controlled object to the implementation of the role of components of the system correction components and testing of the compensation typical aspects of the composition of the measuring element of the control object. Control system design is part of necessary component for completing the work according to the requirements of the production process control system, to determine the link parameters to determine the control method, simulation of system design, calibration to meet the design requirements. Production process on the system stable, fast, accurate and specific indicators to select the appropriate control elements. Automatic control theory of time-domain analysis, root locus method, frequency domain analysis, as )
