algebric loop error while running
显示 更早的评论
An error occurred while running the simulation and the simulation was terminated Caused by: Simulink cannot solve the algebraic loop containing 'untitled/PV Panel/PV Array/Diode Rsh/Product5' at time 0.0004 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('untitled','AlgebraicLoopSolver','LineSearch') b) reducing the ode23t 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.

Add a Delay or Unit Delay block in front of the Product5 block in your model to solve the issue.
