Using loops for simulation in Simulink
2 views (last 30 days)
I have a Simulink model that does arithmetic to calculate value "B". I would like to make use of this value "B" and subtract it from the initial value "A" used in the model. I would like to then use this new calculated value of "A" to do rest of the simulation. When I try to do this by connecting the blocks, I get an error message saying:
"Simulink cannot solve the algebraic loop containing 'Combined/Angle Calculation' at time 0.01 using the TrustRegion-based algorithm due to one of the following reasons: the model is ill-defined i.e., the system equations do not have a solution; or the nonlinear equation solver failed to converge due to numerical issues. To rule out solver convergence as the cause of this error, either a) switch to LineSearch-based algorithm using set_param('Combined','AlgebraicLoopSolver','LineSearch') b) reducing the ode45 solver RelTol parameter so that the solver takes smaller time steps. If the error persists in spite of the above changes, then the model is likely ill-defined and requires modification."
