I need to increase the step size to reduce the data points. But when I changes it from 0.001 to 0.01, errors happen. But for Generation and Sum3, i cannot find a place to change the sample time period. The code is attached. What is the problem ...
// The above approximate logic written in Matlab language; please ask how to implement the function (Voltage Controlled Osillator) with S-Function; the key point is to change the step size; I don't know what the reason is, the code I write with S-Function always...

11、Logic and Bit operations(逻辑&位操作)Compare to constant :与常数比较Compare to zero:与零比较logical operator:逻辑操作算子detect change:监测变化detect decrease:监测减少17SIMULINK仿真的运行启动仿真▪ 设置仿真参数和选择解法器之后,就可以启动仿真而运行。 ▪ 选择Simulink菜单下的start选项来启动仿真,如...
大部分的模型是不需要shape preservation的,只有那些models having signals whose derivative exhibits a high rate of change才适合用shape preservation,而且会增加仿真时长 1.2 fixed-step(定步长) 定步长提供固定的步长,不提供误差控制和过零检测 1.2.1 Solver(算法) ...
11、 step, K is a scaling factor, and Ts is the simulation's discrete step size, which must be fixed. Logic and Bit OperationsCompare To Zero与0进行比较,当为真时输出1,假时输出0;Compare To Constant同上:当输入>constant时输出1,否则为0;Detect Change判断输入函数的值是否等于前一个时刻的值,...
while the solution of interest changes on a much longer time scale. Methods that are not designed for stiff problems are ineffective on intervals where the solution changes slowly because these methods use time steps small enough to resolve the fastest possible change.For more information, seeShampi...
Please change to a working folder that is not in the MAT 2124 carsim吧 ZIP改变 CarSim/Simulink联合仿真报错,求助我先在simulink中新建了一个UniTire轮胎的稳态纵滑侧偏模型,如图: 然后将输入代以一定的数值,仿真不报 +1 分享81 simulink吧 earthwindy相忘 simulink仿真太慢怎么解决?设置了ode23t还是慢 分享...

SIMULINK基础(全)解析 SIMULINK基础 1 概述 在工程实际中，控制系统的结构往往很复杂，如果不借助专用的系统建模软件，很难准确地把一个控制系统的复杂模型输入计算机，对其进行进一步的分析与仿真。1990年，MathWorks软件公司为MATLAB提供了新的控制系统模型图输入与仿真工具，并命名为SIMULAB，该工具很快就在控制工程界...
