MATLAB: Simulink – Triangular wave form simulation

pwmrepeating squencetriangular wave

Hi, I'm trying to generate simple triangular wave and connect the output to a scope.
I used the repeating sequence block and the parameters were set as bellow.
I assume this is something to do with simulation settings.(Continuous function, ODE45)
Furthermore I recieved following warning:Warning: The model 'test22' does not have continuous states, hence Simulink is using the solver 'VariableStepDiscrete' instead of solver 'ode45'. You can disable this diagnostic by explicitly specifying a discrete solver in the solver tab of the Configuration Parameters dialog, or by setting the 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics tab of the Configuration Parameters dialog
Any ideas to fix? thanks

  • I got it working. As suggested updated to fixed step (1/(1000*20)) and selected the solver to discrete.
    thanks
