This model achieves that:[code]model IntegratorWithReset extends Modelica.Blocks.Continuous.Integrator; Modelica.Blocks.Interfaces.BooleanInput reset; equation when reset then reinit (y,y_start); end when; end IntegratorWithReset;... |
Look at the RollingWheel example in Modelica.Mechanics.MultiBody.Examples.Elementary package. Its probably a bit overkill for you since it is a full-fledged 3D mechanical model, but it show the principle of how to add constraints such as a wheel... |
Very nice post! Another suggestion would be to add units to your declared variables. This can be done in two ways. Either you add it explicitly in your declaration e.g.Real V(unit="V",start=0);or you use one of the builtin types in... |
