How to generate a ramp up and ramp down sequence using Matlab Function in Simulink?

In the code i want to accelerate from 300rad/s to 302rad/s from t=5 to t=5.3. Then stay at 302 from t=5.3 to t=6.3. And then decelerate to 300rad/s from t=6.3 to 6.6.
However, I think my code is not right because I have another change in speed before i reached 302. Likewise during the deceleration.

Hi Amadou,
I understand the issue you are facing is that there are two slopes generated in the ramp up and ramp down sections of the signal. One possible workaround is to specify the 'Max step size' option in Solver Configuration Parameters. Specifying a value of 0.1 enables the solver to track the signal changes effectively and only a single slope is obtained as intended. The solver might be missing significant behaviour from the default time step values, so changing the time step value could prevent the solver from taking too large a step.
Regards.
