Firstly,a root-mean-square error is calculated when a DC series motor controlled by the fuzzy controller is in steady state.
首先计算出采用该模糊控制器控制直流串联电机的运行,当电机处于稳定状态时的均方根差;然后与一些文献中给出的具有较好控制品质的模糊控制器加以比较。
A fuzzy model of a direct current series motor was given and a root-mean-square error was used to verify the criterion of 9 fuzzy models.
以直流串联电机为实例,验证了每个模糊控制器的控制品质,其控制品质是通过比较均方根差的大小来衡量的。
The root-mean-square error of this method is less than 0.
所提出的基于粒子滤波的声源定位方法,在高斯噪声情况下,甚至在低信噪比(SNR<-20dB)情况下,定位的均方根误差RMSE值均小于0。
It was found from the comparison chart of the predicted dosage and the actual value and root-mean-square error that the BP model were superior to the linear regression model.
从投药预测值-实际值的对比图和均方根误差等可以看出,BP模型优于回归模型,它通过学习可以根据原水水质进行投药量的有效预测,有一定的自适应性,实用性较强,但也存在一定的局限性,对某些水质的投药预测值还存在一定误差。
A mathematical model to optimize the preloading of large net-shape deployable antennas was established , with the magnitude of the preloading on vertical cables as the design variable, the root mean square on the net-shape reflective surface as the objective function, and the stress and the frequency as constraints.
以纵向拉索预张力的大小为设计变量,网状反射面的均方根误差为目标函数,以应力和频率为约束条件,建立了大型网状可展开天线预张力优化的数学模型,并用遗传算法对其进行了优化。
