利用扩展卡尔曼滤波器,将转速看成一个状态量,根据定子的电流和电压值估算转速。通过仿真对滤波器初值的选取进行了研究,得到优化的卡尔曼滤波器,试验结果表明,速度估算的准确性高,系统对于电机参数的变化不敏感,具有较强的鲁棒性。

We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the problem will simply be the sum of your scores for the individual test cases.

这个连接池是直接从JIVE中取出来的,进行了一下修改,使得连接参数直接在程序中设定而不是从属性文件中读取。 [b]用法:[/b] 先设定自己的连接参数,在DbConnectionDefaultPool.java文件的loadProperties方法中。注意你也需要设定连接池的log文件的存放位置。
