(1) 普通Simulink模块的优先级为Sample Time(Model)> Fixed-step Size(Solver)。有自己的采样时间按自己的来,没有自己的采样时间(采样时间为0或-1)就默认按求解器(Solver)的固定步长来采样; (这边在仿真验证的时候发现一个有趣的现象,当正弦信号采样时间设置为0时,输出波形类似锯齿波;当采样时间设置成-1时,输...
Simulink sets the step size to the fundamental sample time of the model by default. If the model has no discrete rates, Simulink automatically uses the result of dividing the simulation total duration by 50. Consequently, the solver takes a step at each simulation time at which Simulink must ...

What I am trying to understand is that how AUTO step size and enforced step sizes affect simuluation. Does SIMULINK restricts the total number of data points when I set solver to Fixed Step but do not define any step size? Is that why the total number of output data points was t...
With fixed-step zero crossing enabled, Simulink® can automatically detect and locate discontinuities and correct the continuous states in the model. This functionality allows you to use a larger step size and enables faster simulation times without affecting simulation accuracy....
Hi..Can anyone help me in resolving the error i'm getting while running the model? The simulink model is developed in Matlab R2021a version. The model is Grid connected PV system. In this system three controllers are developed i.e, DC Voltage...
When you enable zero-crossing detection, you can sometimes use a larger step size without sacrificing accuracy. When a discontinuity occurs in the simulation, the zero-crossing algorithm calculates the time at which the discontinuity occurred and adjusts the continuous state values accordingly. By adj...
