Error - "Simulink cannot propagate the variable-size mode"
2 views (last 30 days)
I am doing a simple RLC simulation using Simscape and commonly used blocks as shown below,
The block parameters are R = 2ohm, L = 1H, C = 0.2F (initial voltage across capacitor 1V).
and I am getting error as:
In the simulation I used CLK as "t" to represent instantaneous time (u). And the MATLAB fcn block has code which generates the control signal (y) the code is
function y = fcn(u)
y = 0;
y = solveSymsTotal(u);
and in "solveSymsTotal" file has u(t) as given below:
And in Configuration Parameters of SImulation I tried by changing Fixed-Step and Variable-Step both, but still I am getting error.
Also in Simulation I want to plot Phase-trajectory of two states, so I uesd derivative block and XY Graph, but I am unable to find where to give initial Conditions of states? (For capacitor voltage, I mentioned its initial voltage)
Can any one rectify where I am doing wrong?
