1)为了避开出现at time 0 is Inf or NaN。通常给定系统的初始输入为零,若干不长之后(可设成1秒,长短由步长而定),电机仿真模型同样给定初始速度为0.这样是为了给算法模块初始化。2)检查算法是否正确,通常选择的算法是ode45,我们不妨试试刚性算法ode23tb,这在电机仿真中较为常见。当反馈和输...
simulink仿真问题,Derivative input 1 of 's' at time 0.0605 is Inf or NaN. Stopping simulation.请问Derivative input 1 of 's' at time 0.0605 is Inf or NaN. Stopping simulation. There may be a singularity in the solution. If not, try reducing the s

不过从报错上面看,应该是某个数是inf(无穷大)或NaN(无数值)。建议在电机测量后的反馈端加上memory控件。 simulink仿真问题!Derivative input 1 of '' at time 0.0 is Inf or NaN. Stopping simulation. 刚开始的时候初始值为0,0做分母无意义。你可以把分母的初始值额设定一下。 追问:可是他的值本来就是从...
我不知道你的电机仿真是什么样的。不过从报错上面看,应该是某个数是inf(无穷大)或NaN(无数值)。建议在电机测量后的反馈端加上memory控件。
避免/0即可(带除号的模块都要注意)
Simulink软件不允许你设置这个块的初始条件INF或NaN。治疗增益线性时在Simulink软件的线性命令把此块作为一个增益状态空间。选中此复选框导致线性命 令 31、处理增益为1,否则,命令把收益为0。外部机械转矩如果该参数被选中,出现一个S输入名为TM上街区,允许使用外部信号发生器输入机械转矩。这种外部的扭矩必须在普基于...
加了memory之后,就出现这种问题Algebraic state in algebraic loop containing 'test_ben/PV ARRAY/Sum16' computed at time 0.0 is Inf or NaN. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing the fixed step size or by tightenin...
仿真过程中遇到了很打的麻烦,就要交差了,所以来这向大家求助; 采用SIMULINK进行微分方程组求解,设定了初始值,但是在运行过程中会出现Derivative input 1 of block 'untitled4/Integrator2' at time 1 is Inf or NaN. Stopping simulation. There may be a singularity in the solution. If not, try reducing ...
b: 配置参数{Inf or NaN block output} 应设置为Error c:对于R2010b到R2014a,配置参数{Detect overflow}应设置为“Error”,对于R2014b及以后的版本,配置参数{Wrap on overflow} {Saturate on overflow} 应设置为Error 原因 abc:允许检测具有无效值的操作 ...
