We can test the Rate Limiter block with the Colink model shown in the below figure The Sine block is configured to a frequency of 1rad/sec and an amplitude of 3. The Rate Limiter block Rising rate is set to 1 and Falling rate is set to -1. Initial Condition is set to 1. Set solver type to Fixed-Step, discrete (no continuous states), and let End time be 10.
