20.6.6.4. Limiter

The Limiter block imposes upper and lower limits. If the input signal is between the Upper and Lower limit values, the output signal is equal to the input signal. If the input signal is greater than the Upper value or less than the Lower value, the output signal is the Upper value or the Lower value, respectively.

Parameter(s)	Description
Upper	Enter the upper limit.
Lower	Enter the lower limit.
Sample time	Enter the time interval between samples.

20.6.6.4.1. Example

We can test the 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 1. The Limiter block Lower is set to -0.5 and Upper is set to 0.5. Set solver type to Fixed-Step, discrete (no continuous states), and let End time be 1.
