1、修改仿真步长、限幅等 2、将连续的改为离散的 报错: Derivative of state '1' in block 'xxx/xxx/Integrator/Continuous/Integrator' at time 0.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducin...
A range of bicyclic phosphates (154; X = Y = O) have been the subject of biological assessment 〈82ABC411〉, and a 1-hydroxmethyl derivative (154; X = Y = O; R = HOCH2) has been patented for its herbicidal properties 〈66USP3287448〉. The effects of various drug pretreatments on...

Protein with a known function is 58% in chromosome 1, which is required for proper functioning of the cell and 48% in chromosome 2. The proteins with unknown functions are 6 in both chromosome 1 and 2. The genomic sequence of V. cholerae is confirmed by the presence of a large i...
In this work, we investigate a linear differential equation involving Caputo-Fabrizio fractional derivative of order 1 < β≤ 2. Under some assumptions the considered equation is reduced to an integer order differential equation and solutions for different cases are obtained in explicit forms. We als...
1、可以在simulation下拉菜单中congfiguration parameters减小步长 2、在simulation/configuration Parameters中sovers中sover options type选fixed type 提示的意思是在迭代中可能出现了某个奇异点，导致无法收敛。如果算法上没有问题的话 可能每次的增进步阶因子取的不合适导致过调。比如因子过大会导致越过极值...
The presence of galactofuranoyl units in infectious microorganisms has prompted the study of the metabolic pathways involved in their incorporation in glycans. Although much progress has been made with respect to the biosynthesis of #946;-D-Galif/i-containing glycoconjugates, the mechanisms by which...
Derivative of state ‘1‘ in block ‘untitled/PID/Integrator‘ at time 0.0 is not finite.,程序员大本营,技术文章内容聚合第一站。
I need help figuring out why I am getting the error message: "Derivative of state '1' in block'SimulinkModel/EQ2 Intergrator'at time 0.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing ...
Derivative of state '1' in block ~ at time 0.0 is not finite. 积分状态变量数据奇异问题的一种解决方案 本解决方案针对出现除法器分母为0的问题。 由于处于分母状态的信号初始时刻存在一小段为0的状态,导致除法器后的值有一段无穷大的数值,从而又导致加入惯性环节这一连续传递函数后simulink无法运行。
